Heterosexual Aversion in Homosexual Males A Second Experiment
KURT FREUND, RON LANGEVIN, YAROSLAW ZAJAC

Abstract

Part One of the study showed that homosexual and heterosexual males respond with penile tumescence to pictures of isolated parts of the body of their preferred sex. In Part Two, homosexual males who had been pre-aroused by pictures of male nudes did not respond to pictures of the vulva, the face or the breasts of the mature female with penile volume changes different from those in response to sexually neutral slides. However, in terms of ratings on a four-point scale for disgust, the vulva was rated significantly more disgusting than the breasts, which in turn were rated significantly more disgusting than the face and the sexually neutral pictures.
