Abstract
Research on sexual orientation attempts to reduce it to a monocausal phenomenon, whether that be biology (genes, hormones) or social environment (parenting patterns). None of these fully accounts for the diversity of erotic attraction and behavior, and indeed these reductionist strategies either misrepresent many forms of sexual behavior or erase them from our ontology. Understanding is better served by first acknowledging the variety of roles of sexual interaction in human life, rather than treating sex as a single kind of phenomenon.
