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)

Many people believe that a person's sexual orientation is genetic. Given the widespread prejudice against, and hatred of, homosexuals in many societies, it seems likely that many parents will be interested in using genetic technologies to prevent the birth of children who will not be heterosexual.

It is argued that the availability of procedures to select the sexual orientation of children would contribute to (...) discrimination and prejudice against lesbians, gay men and bisexuals and, more generally, undermine the maintenance of a just society. These effects carry significant weight in determining whether genetic technologies should be developed and whether their use is, or should be, legally permissible and morally acceptable. (shrink)
