In men and women sexual arousal culminates in orgasm, with female orgasm solely from sexual intercourse often regarded as a unique feature of human sexuality. However, orgasm from sexual intercourse occurs more reliably in men than in women, likely reflecting the different types of physical stimulation men and women require for orgasm. In men, orgasms are under strong selective pressure as orgasms are coupled with ejaculation and thus contribute to male reproductive success. By contrast, women's orgasms (...) in intercourse are highly variable and are under little selective pressure as they are not a reproductive necessity. The proximal mechanisms producing variability in women's orgasms are little understood. In 1924 Marie Bonaparte proposed that a shorter distance between a woman's clitoris and her urethral meatus (CUMD) increased her likelihood of experiencing orgasm in intercourse. She based this on her published data that were never statistically analyzed. In 1940 Landis and colleagues published similar data suggesting the same relationship, but these data too were never fully analyzed. We analyzed raw data from these two studies and found that both demonstrate a strong inverse relationship between CUMD and orgasm during intercourse. Unresolved is whether this increased likelihood of orgasm with shorter CUMD reflects increased penile–clitoral contact during sexual intercourse or increased penile stimulation of internal aspects of the clitoris. CUMD likely reflects prenatal androgen exposure, with higher androgen levels producing larger distances. Thus these results suggest that women exposed to lower levels of prenatal androgens are more likely to experience orgasm during sexual intercourse. . (shrink)

Human beings talk and co-operate, they build and produce, they work to accumulate and exchange, they form societies, laws and institutions, and, in all these things the phenomenon of reason—as a distinct principle of activity—seems dominant.

Background: Human sexual classical conditioning effects are less robust compared with those obtained in other animals. The artificiality of the laboratory environment and/or the unconditioned stimulus (US) used (e.g. watching erotic film clips as opposed to participating in sexual activity) may contribute to this discrepancy. The present experiment used a field study design to explore the conditioning of human sexual arousal. Method: Seven heterosexual couples were instructed to include a novel, neutrally preferred scent as the conditioned (...) stimulus (CS+) during sexual interaction and another novel scent during non-sexual coupledinteraction (e.g. watching a movie, studying together). Seven control couples used both scents during nonsexual interaction. Conducted over a 2-week period, both experimental and control couples had three sexual interactions (oral sex and/or intercourse). In addition, experimental couples had three, while the controls had six, non-sexual interactions. Genital responding to and affective preference for the odors were assessed in the laboratory before and after the experience in the men. Results: We observed significantly increased genital responding to the CS+in the experimental relative to the control group; however, conditioned responses were not much stronger than those obtained during laboratory conditioning. Experimental males also showed a trend for decreased preference for the CS-odor. They may have learned that this odor predicted that sexual interaction with their partner would not occur. Conclusion: The present study provides another demonstration of conditioned sexual arousal in men, specifically an instance of such learning that happened in a real-world setting. It also suggests that inhibitory learning may occur, at least with the affective measure.

As state-of-art technology can create artificial images that are indistinguishable from real ones, it is urgent to understand whether believing that a picture is real or not has some import over affective phenomena such as sexual arousal. Thus, in two pre-registered online studies, we tested whether 60 images depicting models in underwear elicited higher self-reported sexual arousal when believed to be (N = 57) or presented as (N = 108) real photographs as opposed to artificially generated. (...) In both cases, Realness correlated with significantly higher scores on self-reported sexual arousal. Consistently with the literature on downregulation of emotional response to fictional works, our result indicates that sexual images that are perceived to be fake are less arousing than those believed to portray real people.

The past 20–30 years have provided plenty of new empirical data on women’s sexuality, a topic often theorised as puzzling and unexplainable. In recent discussions, a controversial issue has been the phenomenon of sexual concordance, i.e. the correlation between the self-reported, subjective assessment of one’s sexual arousal and the simultaneous bodily response measured directly on the genitals. In laboratory-based assessments, sexual concordance has been observed to be on average substantially lower in women than in men, although (...) the reasons for the considerable gender difference are still open to debate. Drawing on a phenomenological approach to culture-dependent meaning-formation and on feminist social theory of everyday sexuality, I argue that the reasons behind women’s low sexual concordance can be found neither in their minds nor their bodies but in the way meaning-making processes function in human sexual experiences. Women’s first-person perspectives on their own sexuality have historically played only a marginal role in the creation of socially endorsed sexual meanings, yet these shared meanings have a profound influence on how individuals make sense of their bodily experiences in sexual situations.

Medicalisation is a social phenomenon in which conditions that were once under legal, religious, personal or other jurisdictions are brought into the domain of medical authority. Low sexual desire in females has been medicalised, pathologised as a disease, and intervened upon with a range of pharmaceuticals. There are two polarised positions on the medicalisation of low female sexual desire: I call these the mainstream view and the critical view. I assess the central arguments for both positions. Dividing the (...) two positions are opposing models of the aetiology of low female sexual desire. I conclude by suggesting that the balance of arguments supports a modest defence of the critical view regarding the medicalisation of low female sexual desire. (shrink)

This paper proposes that the human mind in its creativity and emotional self-awareness is the result of the evolutionary transition from sexuality to eroticism. Eroticism is arrived at and defined by the high amount of energy displayed in animal sexuality. We propose that the unique human emotional intelligence is due to this “overflow” of mating energy. What from the survival viewpoint looks like an enormous waste of time and energy reveals itself to be an unexpected psychological benefit. The diversion of (...) sexual energy from procreation — a process that results in erotic fantasies — turns intimacy into a source of human self -consciousness. This places different emphasis on the meaning of eroticism and provides a coherent scenario of mental development beyond mere cognitive capacities. Arguments are presented on how erotic imagination, or sexual excitation as an end in itself, promotes the human propensity for explorative curiosity; data from ethology, psychology, sociology, and neuroscience are presented to support these arguments. As philosophical anthropologists, we do not provide new empirical data, but the available results of comparative behavioral research confirm our hypothesis. (shrink)

Based on its prevalence, there is an urgent need to better understand the mechanisms, opportunities and risks of sexual interaction in digital contexts that are related with sexual arousal. While there is a growing body of literature on SIDC, there is also a lack of conceptual clarity and classification. Therefore, based on a conceptual analysis, we propose to distinguish between sexual interaction through, via, and with digital technologies. Sexual interactions through digital technologies are face-to-face (...) class='Hi'>sexual interactions that have been started digitally or are accompanied by digital technology. Sexual interactions via digital technology are technology-mediated interpersonal sexual interactions. Sexual interactions with digital technology occur when the technology itself has the role of an interaction partner. The three types of SIDC and their respective subtypes are explained and backed up with empirical studies that are grouped according to two major mediators: consent and commerce. Regarding the causes and consequences of the three types of SIDC we suggest a classification that entails biological, psychological, social, economic, and technological factors. Regarding implications of SIDC we suggest to focus on both opportunities and risks for sexual health. The proposed conceptual framework of SIDC is meant to inform future research. (shrink)

A dazzling treatise, as erudite and eloquent as Simone de Beauvoir's The Second Sex and considerably more sound in its conclusion - TLS "He is an eloquent and practised writer" - The Independent (UK) When John desires Mary or Mary desires John, what does either of them want? What is meant by innocence, passion, love and arousal, desire, perversion and shame? These are just a few of the questions Roger Scruton addresses in this thought-provoking intellectual adventure. Beginning from purely (...) philosophical premises, and ranging over human life, art and institutions, he surveys the entire field of sexuality; equally dissatisfied with puritanism and permissiveness, he argues for a radical break with recent theories. Upholding traditional morality - though in terms that may shock many of its practitioners - his argument gravitates to that which is candid, serene and consoling in the experience of sexual love.

What is sexual orientation? The contemporary consensus among philosophers is that it is a disposition. Unsurprisingly, recent debates about the metaphysics of sexual orientation are almost entirely intramural. Behavioral dispositionalists argue that sexual orientation is a disposition to behave sexually. Desire dispositionalists argue that it is a disposition to desire sexually. We argue that sexual orientation is not best understood in terms of dispositions to behave or dispositions to desire before arguing that dispositions tout court fail (...) to illuminate sexual orientation. We then introduce and defend the idea that sexual orientation is best understood in terms of categorical phenomenal properties of sexual arousal. (shrink)

Numerous studies have found that many people believe that a provocatively dressed woman is at greater risk for sexual assault and bears some responsibility for her assault if she is attacked. Furthermore, in legal, academic, and public debates about sexual assault the appropriateness of the term ‘provocative’ as a descriptor of certain kinds of women’s clothing is rarely questioned. Thus, there is a widespread but largely unquestioned belief that it is appropriate to describe revealing or suggestive women’s clothing (...) as ‘provocative’ and that women who wear such clothing could provoke sexual assault and harassment from men. Yet it is rarely noted that only women’s clothing is described as sexually provocative. Men’s clothing, no matter how revealing, is never described as provocative. Why is this the case? This Article challenges the assumption that it is appropriate to describe women’s clothing as provocative. Drawing on on models of the legal defense of provocation and research on objectification and responsibility, this Article demonstrates that continued use of ‘provocative’ term normalizes and entrenches deeply problematic attitudes about women’s responsibility for men’s sexual behavior. The social interpretation of women’s clothing as provocative arises from the privileged social and legal status of men’s sexual arousal and the objectification of women’s bodies. Describing women’s clothing as provocative thus reinforces a problematic conception of women’s bodies and sexuality that is connected to women’s experiences of their bodies, their clothes, and shapes their vulnerability to sexual assault and social and legal attitudes to such attacks.

Sexual fantasy is a non-perceptual thought that is sexually arousing. It has several paradigmatic features. The structure of a fantasy involves an agent taking pleasure in an object that is often a visual depiction of an event. The fantasy is under the agent’s control and has a semantic content. Since mere sexual fantasizing about someone respects the individual who are depicted in the fantasy, the rightness of a sexual fantasy depends on whether consequentialism is true and, if (...) so, whether the particular fantasy brings about better results an alternative activities. Sexual fantasies can be intrinsically good or bad depending on whether the pleasure is malicious and whether the fantasy contains a false statement. The vast majority are not intrinsically bad since they neither involve an unfitting attitude toward something that is itself bad nor commit the subject to a falsity. Hence, if one rejects consequentialism, then most sexual fantasies, including many of the most violent ones, are neither wrong nor intrinsically bad. (shrink)

Patterns in the data on human sexuality support the hypothesis that the bases of sexual emotions are products of natural selection. Most generally, the universal existence of laws, rules, and gossip about sex, the pervasive interest in other people's sex lives, the widespread seeking of privacy for sexual intercourse, and the secrecy that normally permeates sexual conduct imply a history of reproductive competition. More specifically, the typical differences between men and women in sexual feelings can be (...) explained most parsimoniously as resulting from the extraordinarily different reproductive opportunities and constraints males and females normally encountered during the course of evolutionary history. Men are more likely than women to desire multiple mates; to desire a variety of sexual partners; to experience sexual jealousy of a spouse irrespective of specific circumstances; to be sexually aroused by the sight of a member of the other sex; to experience an autonomous desire for sexual intercourse; and to evaluate sexual desirability primarily on the bases of physical appearance and youth.The evolutionary causes of human sexuality have been obscured by attempts to find harmony in natural creative processes and human social life and to view sex differences as complementary. The human female's capacity for orgasm and the loss of estrus, for example, have been persistently interpreted as marriage-maintaining adaptations. Available evidence is more consistent with the view that few sex differences in sexuality are complementary, that many aspects of sexuality undermine marriage, and that sexuality is less a unifying than a divisive force in human affairs.

The sexuality of young people arouses controversy and remains a source of concern for parents, teachers, policy-makers and politicians. But what young people really think about sexuality and gender and how these issues impact upon their lives is often marginalized or overlooked. Based upon extensive ethnographic research with young people and teachers, _Sexuality, Gender and Schooling_ offers a telling and insightful account of how young people acquire sexual knowledge and how they enact their understanding of their own gender. It (...) highlights the ways in which young people's constructions of gender and sexuality are formed outside the school curriculum, through engagements with various forms of popular culture - such as teen magazines and television programmes - and through same-sex friendship groups. Offering a fresh perspective on a subject of perennial interest and concern, _Sexuality, Gender and Schooling_ provides accounts from the inside - some of which may challenge and eclipse current approaches to sexuality education. It has significant implications for policy and practice in Personal, Social and Health Education and is also an excellent introduction to key debates and issues in the study of gender and sexuality.

A number of theories about the origins of musicality have incorporated biological and social perspectives. Darwin argued that musicality evolved by sexual selection, functioning as a courtship display in reproductive partner choice. Darwin did not regard musicality as a sexually dimorphic trait, paralleling evidence that both sexes produce and enjoy music. A novel research strand examines the effect of musicality on sexual attraction by acknowledging the importance of facial attractiveness. We previously demonstrated that music varying in emotional content (...) increases the perceived attractiveness and dating desirability of opposite-sex faces only in females, compared to a silent control condition. Here, we built upon this approach by presenting the person depicted (target) as the performer of the music (prime), thus establishing a direct link. We hypothesized that musical priming would increase sexual attraction, with high-arousing music inducing the largest effect. Musical primes (25 s, piano solo music) varied in arousal and pleasantness, and targets were photos of other-sex faces of average attractiveness and with neutral expressions (2 s). Participants were 35 females and 23 males (heterosexual psychology students, single, and no hormonal contraception use) matched for musical background, mood, and liking for the music used in the experiment. After musical priming, females’ ratings of attractiveness and dating desirability increased significantly. In males, only dating desirability was significantly increased by musical priming. No specific effects of music-induced pleasantness and arousal were observed. Our results, together with other recent empirical evidence, corroborate the sexual selection hypothesis for the evolution of human musicality. (shrink)

Background: The development of implicit tests for measuring biases and behavioral predispositions is a recent development within psychology. While such tests are usually researched within a social-cognitive paradigm, behavioral researchers have also begun to view these tests as potential tests of conditioning histories, including in the sexual domain. Objective: The objective of this paper is to illustrate the utility of a behavioral approach to implicit testing and means by which implicit tests can be built to the standards of behavioral (...) psychologists. Design: Research findings illustrating the short history of implicit testing within the experimental analysis of behavior are reviewed. Relevant parallel and overlapping research findings from the field of social cognition and on the Implicit Association Test are also outlined. Results: New preliminary data obtained with both normal and sex offender populations are described in order to illustrate how behavior-analytically conceived implicit tests may have potential as investigative tools for assessing histories of sexual arousal conditioning and derived stimulus associations. Conclusion: It is concluded that popular implicit tests are likely sensitive to conditioned and derived stimulus associations in the history of the test-taker rather than ‘unconscious cognitions’, per se.

The primary purpose of depictive works of pornography, we take it, is sexual arousal through sexually explicit representations; what we callprototypical pornography satisfies those aims through the adoption of a ceteris paribus maximally realistic depictive style. Given that the purpose of sexual arousal seems best fulfilled by establishing the most robust connections between the viewer and the depictive subject, we find it curious that not all works of pornography aspire to prototypical status. Accordingly, we target for (...) philosophical scrutiny several non-standard but putatively pornographic forms: Tijuana Bibles, hentai manga, and slash-fiction. We find that works of these genres possess certain depictively or fictively oriented properties that appear at least prima facie incompatible with prototypical pornography, and thereby to pose two pressing questions that anyprima facie viable analysis of pornography must answer: the depiction question and the fiction question. By answering these questions, we can not only arrive at a deeper understanding of the aims of pornography and the reasons for which significant sub-genres of pornography might diverge from the prototypical ideal, but also perhaps better understand what lies at pornography’s edge, and so better understand the ways in which pornography might relate to what lies beyond.

In Sri Lanka’s armed conflict, gender, sexuality, and sex work are intermeshed with militarized nationalism. Militarization entrenches gender performances and heteronormative schemes while enabling women to transgress these—whether as combatants or as sex workers. Familiarly, in this nationalist encounter, women are expected to safeguard culture, notably through proper dress and sexual conduct. Sexualactivity that challenges containment arouses anxiety because loyalty to military groupor communal boundary can be compromised. Drawing on three examples—adress codecall by a Liberation Tigers of Tamil Eelam (...) women’s wing, consequences for a woman alleged to be a sex worker, and the public stripping of an alleged suicide bomber at a military checkpoint—this article explores how gendered behaviors and sexualities marked as culture are constructed and controlled in the interests of militarized, nationalist projects; how women can be both agents and objects of these controls; and the implications for women who refuse to comply.

Because technologies are frequently used for sexual gratification it seems plausible that artificial communication partners, such as voice assistants, could be used to fulfill sexual needs. While the idea of sexualized interaction with voice assistants has been portrayed in movies, there is a lack of empirical research on the effect of the ontological class on the voice’s potential to evoke interest in a sexualized interaction and its perception in terms of sexual attractiveness. The Sexual Interaction Illusion (...) Model, which emphasizes influences on sensations evoked by artificial interaction partners, furthermore suggests that there may be contextual influences, especially sexual arousal, that may be crucial for the question of engaging in a sexualized interaction with an artificial entity. To empirically investigate whether the ontological class of the speaker and the level of sexual arousal affects the heterosexual males’ interest in hearing more flirtatious messages and the perception of the communication partner’s sexual attractiveness, an online experiment with between subject design was conducted. Two hundred and fifty seven respondents were confronted with at least four, and voluntarily six messages from either a computer-mediated human or a flirtatious voice assistant, in interaction with being previously primed sexually or neutrally. The results demonstrated that the effect of sexual arousal was not prevailing on the interest in further messages and the attractiveness perception of the interaction partners, while the ontological class did so. Here, the voice assistant evoked more interest in further messages and the technology itself, while the computer mediated human was perceived to be more sexually attractive and flirtatious, and evoked more social presence. The communication partners social presence was shown to be the predictor with most explanatory power for the interaction partners perceived sexual attractiveness, regardless of whether it was human or artificial. The results underline differences between artificial and human interaction partners, but also underline that especially social presence and the feeling that the user is addressed is crucial in digitalized intimacy regardless of the ontological class.

Background: We like to think about sexual activity as something fixed, basic and primal. However, this does not seem to fully capture reality. Even when we relish sex, we may be capable of mentalizing, talking, voluntarily postponing orgasm, and much more. This might indicate that the central control mechanisms of sexual activity are quite flexible and susceptible to learning mechanisms, and that cortical brain areas play a critical part. Objective: This study aimed to identify those cortical areas and (...) mechanisms most consistently implicated in sexual activity. Design: A comprehensive review of the human functional neuroimaging literature on sexual activity, i.e. genital stimulation and orgasm, is made. Results: Genital stimulation recruits the classical somatosensory matrix, but also areas far beyond that. The posterior insula may be particularly important for processing input from the engorged penis and coordinating penile responses. Extrastriate visual cortex tracks sexual arousal and responds to genital stimulation even when subjects have their eyes closed. The ventromedial prefrontal cortex is also tightly coupled to sexual arousal, but low activity in this area predicts high sexual arousal. Conclusion: This review has indicated cortical sites where activity is moderated by tactile genital inflow and high sexual arousal. Behavioral implications are discussed and where possible the relevance for learning mechanisms is indicated. Overall, it is clear that the cerebral cortex has something to say about sexual activity.

In Archaic Athenian vase-painting, silens are often sexually aroused, but only sporadically satisfy their desires in a manner acceptable to most Athenian men. François Lissarrague persuasively argued that the sexuality of silens in vase-painting was probably laughable rather than awe-inspiring. What sort of laughter did the vase-paintings elicit? Was it the scornful laughter of a person who felt nothing in common with silens, or the laughter of one made to see something of himself in their behavior? For three reasons, I (...) argue for the latter interpretation. First, some vase-paintings are constructed so as to invite the viewer to adopt imaginatively the persona of a silen. Second, parallels for the less-than-triumphant sexuality of silens occur in Archaic iambic poetry. Like the vase-paintings, the poetry was often constructed so that performers of the poems are incorporated into the narratives as all-too-human protagonists. Third, certain formal features of classical satyr-play encouraged the audience to identify with the point of view of the satyr-chorus, while others reminded it that there were better role models than silens. In all three media, a negative characterization of male characters or silens is combined with a manner of presentation that invites the viewer or performer to see himself among those characters despite their negative traits. That form of humor may have been common in Archaic symposia, but its presence in satyr-play suggests that it may also be a fundamental characteristic of silens. (shrink)

A developmental theory of erotic/romantic attraction is presented that provides the same basic account for opposite-sex and same-sex desire in both men and women. It proposes that biological variables, such as genes, prenatal hormones, and brain neuroanatomy, do not code for sexual orientation per se but for childhood temperaments that influence a child's preferences for sex-typical or sex-atypical activities and peers. These preferences lead children to feel different from opposite-or same-sex peers — to perceive them as dissimilar, unfamiliar, and (...) exotic. This, in turn, produces heightened nonspecific autonomic arousal that subsequently gets eroticized to that same class of dissimilar peers: Exotic becomes erotic. Specific mechanisms for effecting this transformation are proposed. The theory claims to accommodate both the empirical evidence of the biological essen-. (shrink)

Post-traumatic stress disorder is a “young” disorder formally recognized in the early 1980s, although the symptoms have been noted for centuries particularly in relation to military conflicts. PTSD may develop after a serious traumatic experience that induces feelings of intense fear, helplessness or horror. It is currently characterized by three key classes of symptoms which must cause clinically significant distress or impairment of functioning: persistent and distressing re-experiencing of the trauma; persistent avoidance of stimuli associated with the trauma and numbing (...) of general responsiveness; and persistent symptoms of hyper-arousal. One of the possible symptoms within the second class is difficulty in remembering an important aspect of the traumatic event.PTSD is not an uncommon condition, with an estimated lifetime prevalence of about 7-9% based on studies conducted in the United States and Canada, with women at higher risk than men. While not everyone who experiences a significant trauma will go on to develop PTSD, about a third will do so. Sexual assault, along with other forms of assaultive violence, pose a comparatively high risk of PTSD. (shrink)

In this address, I outline my “Exotic-Becomes-Erotic" theory of sexual orientation (Bem, 1996) , which provides the same basic account for both opposite-sex and same-sex erotic desire—and for both men and women. It proposes that biological variables do not code for sexual orientation per se but for childhood temperaments that influence a child’s preferences for sextypical or sex-atypical activities. These preferences lead children to feel different from opposite-sex or same-sex peers—to perceive them as “exotic.” This, in turn, produces (...) heightened physiological arousal that subsequently gets eroticized to that same class of peers: Exotic becomes erotic. The theory claims to accommodate both the empirical evidence of the biological essentialists and the cultural relativism of the social constructionists. I also discuss sex differences in sexual orientation and the political implications of trying to explain homosexuality. (shrink)

Male sexual arousal (SA) has been known as a multidimensional experience involving closely interrelated and coordinated neurobehavioral components that rely on widespread brain regions. Recent functional neuroimaging studies have shown relation between abnormal/altered dynamics in these circuits and male sexual dysfunction. However, alterations in the topological1 organization of structural brain networks in male sexual dysfunction are still unclear. Here, we used graph theory2 to investigate the topological properties of large-scale structural brain networks, which were constructed using (...) inter-regional correlations of cortical thickness between 78 cortical regions (subcortical regions were not included due to the used cortical surface model) in 40 patients with psychogenic erectile dysfunction (pED) and 39 normal controls. Compared with normal controls, pED patients exhibited a less optimal global topological organization with reduced global and increased local efficiencies. Our results suggest disrupted neural integration among distant brain regions in pED patients, consistent with previous reports of impaired white matter structure and abnormal functional integrity in pED. Additionally, disrupted global network topology in pED was observed to be primarily relevant to altered subnetwork and nodal properties within the networks mediating the cognitive, motivational and inhibitory processes of male SA, possibly indicating disrupted integration of these networks in the whole brain networks and might account for pED patients’ abnormal cognitive, motivational and inhibitory processes for male SA. In total, our findings provide evidence for disrupted integrity in large-scale brain networks underlying the neurobehavioral processes of male SA in pED and provide new insights into the understanding of the pathophysiological mechanisms of pED.

In lieu of an abstract, here is a brief excerpt of the content:Erotic Art and Pornographic PicturesJerrold LevinsonOnly in primitive art, with its urgent need to evoke the sources of fertility, are the phallus and the vulva emphasized, as it were innocently. By ancient Greek and Roman times there already existed the special category of the pornographic—graphic art or writing supposed, like a harlot, or porne, to sexually stimulate.1IAS REGARDS PHILOSOPHICAL ANALYSIS of the opposition between the erotic and the pornographic, (...) there are a number of reasonable goals one might have: to preserve as many considered intuitions about the opposition as possible; to present the opposition in a clearer light than it enjoys when casually invoked; to modestly "sharpen" the standard opposition that either accounts for our experience in this domain more fully, or allows us to organize our thinking about the domain more perspicuously. I hope in this paper to make progress toward some of those goals. Though the scope of the erotic/pornographic opposition goes beyond the visual, my focus here will be the opposition as it exists in the visual sphere, and even more narrowly, in the sphere of images. In addition to preserving and clarifying a distinction between erotic art and pornography, I hope also to make an intelligible place for erotica, as something intermediate between the other two.Here, then, are some intuitions on the erotic and the pornographic: [End Page 228]1. the erotic and the pornographic are both concerned with sexual stimulation or arousal.2. while the term "erotic" is neutral or even approving, the term "pornographic" is pejorative or disapproving.3. while "erotic art" is a familiar, if somewhat problematic, notion, "pornographic art" seems an almost oxymoronic one.4. whereas pornography has a paramount aim, namely, the sexual satisfaction of the viewer, erotic art, even if it also aims at sexual satisfaction on some level, includes other aims of significance.5. whereas we appreciate (or relish) erotic art, we consume (or use) pornography. In other words, our interactions with erotic art and pornography are fundamentally different in character, as reflected in the verbs most appropriate to the respective engagements.In what follows I try to accommodate all of those intuitions. As I will need a distinction invoked in the first of them (between sexual stimulation and sexual arousal) let me spell that out before proceeding. By sexual stimulation I will mean the inducing of sexual thoughts, feelings, imaginings, or desires that would generally be regarded as pleasant in themselves. By sexual arousal I mean the physiological state that is prelude and prerequisite to sexual release, involving in the male, at least, some degree of erection. And by sexual release I mean something that I take it needs no spelling out.How to differentiate erotic art from pornography, and from erotica as well, is of course not the only important philosophical question about erotic art. Here are two others: 1) How is the erotic aspect of erotic art compatible with the disinterested or distanced frame of mind that seems required for aesthetic engagement with or appreciation of a work of visual art? 2) How is the degree of eroticness of a work of erotic art related to its artistic value? I will briefly address those two questions toward the end of the paper, but most of my effort will be devoted to the prior question, that of the differentiation of erotic art, erotica, and pornography.IIHow, then, to effect that differentiation in the domain of visual images to which I have restricted my inquiry? One possibility would [End Page 229] concern the specific kind of response aimed at. Thus, erotic art might be said to involve images intended to sexually stimulate, but also to reward artistic interest; erotica to involve images intended to sexually stimulate but not to reward artistic interest; pornography to involve images intended to sexually arouse in the interests of sexual release. Another possibility would be by the character of the sexual representation involved, so that pornography would involve sexually explicit images, erotic art would involve sexually inexplicit images, and erotica images would be intermediate in their explicitness, irrespective of the ends for which the images were fashioned. A third possibility would be by... (shrink)

The received view holds that pornographic representations can only be bad art. Three arguments for this view are examined based on definitional considerations, the purpose of sexual arousal being inimical to the realization of artistic value, the problem of appreciating a work as pornography and as art. It is argued not only that the received view is without warranty but, moreover, that there are works which are only properly appreciable as pornographic art.

Evolutionary approaches to the emotions have traditionally focused on a subset of emotions that are shared with other species, characterized by distinct signals, and designed to solve a few key adaptive problems. By contrast, an evolutionary psychological approach broadens the range of adaptive problems emotions have evolved to solve, includes emotions that lack distinctive signals and are unique to humans, and synthesizes an evolutionary approach with an information-processing perspective. On this view, emotions are superordinate mechanisms that evolved to coordinate the (...) activity of other programs in the solution of adaptive problems. We illustrate the heuristic value of this approach by furnishing novel hypotheses for disgust and sexual arousal and highlighting unexplored areas of research. (shrink)

Background. Although genital sensations are an essential aspect of sexual behavior, the cortical somatosensory representation of genitalia in women and men remain poorly known and contradictory results have been reported. Objective. To conduct a systematic review of studies based on electrophysiological and functional neuroimaging studies, with the aim to identify insights brought by modern methods since the early descriptions of the sensory homunculus in the primary somatosensory cortex . Results. The review supports the interpretation that there are two distinct (...) representations of genital sensations in SI, one on the medial surface and the other on the lateral surface. In addition, the review suggests that the secondary somatosensory cortex and the posterior insula support a representation of the affective aspects of genital sensation. Conclusion. In view of the erogenous character of sensations originating in the genitalia, future studies on this topic should systematically assess qualitatively as well as quantitatively the sexually stimulating and/or sexually pleasurable characteristics of sensations felt by subjects in response to experimental stimuli.

Circumcision of males represents a surgical “vaccine“ against a wide variety of infections, adverse medical conditions and potentially fatal diseases over their lifetime, and also protects their sexual partners. In experienced hands, this common, inexpensive procedure is very safe, can be pain‐free and can be performed at any age. The benefits vastly outweigh risks. The enormous public health benefits include protection from urinary tract infections, sexually transmitted HIV, HPV, syphilis and chancroid, penile and prostate cancer, phimosis, thrush, and inflammatory (...) dermatoses. In women circumcision of the male partner provides substantial protection from cervical cancer and chlamydia. Circumcision has socio‐sexual benefits and reduces sexual problems with age. It has no adverse effect on penile sensitivity, function, or sensation during sexual arousal. Most women prefer the circumcised penis for appearance, hygiene and sex. Given the convincing epidemiological evidence and biological support, routine circumcision should be highly recommended by all health professionals.

Philosophers involved in the ‘porn-or-art’ debates standardly assume that pornography is centrally about sexual arousal, while art is about something else. I argue against this assumption and for the view that there is no single thing that pornography (or art) ‘is about’. This suggests that there is no prima facie reason for claiming that some x cannot be both pornography and art. I further go on to develop an understanding of (what I call) ‘porno-art’ - a wholly new (...) kind of thing developing from the extant categories of pornography and art, but still distinct and separate from them.
