Abstract

Heterosexuality, which I define as a romantic and sexual orientation toward persons not of one's own sex, is apparently a very general, though not entirely universal, characteristic of the human condition. In fact, it is so ubiquitous a part of human interactions and relations as to be almost invisible, and so natural-seeming as to appear unquestionable. Indeed, the 1970 edition of The Shorter Oxford English Dictionary defines ‘heterosexual’ as ‘pertaining to or characterized by the normal relation of the sexes.’
