The definite and persistent phenomenon of sexual assault upon males is virtually ignored in the literature, although incidence data reported here suggest the greater scope of the problem. The avoidance of the subject of sexual assault on males creates a negative environment for victims. While the motivation of assailants is briefly discussed, the article focuses on the psychological aftermath for sexual assault victims. A paradigm is offered, consisting of "Set-up," "Attack," and "Aftermath" phases. Male victims suffer "Rape Trauma Syndrome" as described for females, as well as various forms of stigmatization and secondary trauma. Differences and similarities between male and female victims are identified. Victim responses are discussed as they proceed through several stages, with implications for appropriate interventions on both the clinical and community levels. The article concludes with an extensive bibliography.
