Although men are far less likely than women to be victims of heterosexual assault, such cases have been reported with increasing frequency in recent years. We compared social judgments about male and female victims of heterosexual and homosexual rape and tested hypotheses concerning social cognitions that are assumed to underlie a male rape mythology. In a 2×2×2 design, 77 male and 89 female subjects made a series of judgments about a sexual assault case in which sex of victim and sex of assailants were manipulated. Consistent with the hypotheses, the male victim of sexual assault by females was judged more likely to have initiated or encouraged the sex acts, and more enjoyment and less stress were attributed to him. This pattern of results was more pronounced among male subjects. The results are discussed in relation to stereotypic beliefs concerning male sex roles, sexual motivation, and sexual functioning that are likely to affect the social cognitions of both observers and male victims of heterosexual assault.
