Twenty-nine men, ranging in age from 18 to 65, who were victims of sexual assault or attempted sexual assault, were seen over a 16-month period. Information extracted from the unit database included client demographics and personal history, assault characteristics, and presentation information. Twenty-five of the reported assaults involved male perpetrators, one involved a single female perpetrator, and two involved both male and female perpetrators. Half the male-male assaults and all the female-male assaults were acquaintance sexual assaults. Only a minority of the stranger assaults were suggestive of antigay violence. Most victims were young gay men, many of whom had physical or cognitive disabilities making them particularly vulnerable. The results suggest a need for increased awareness of acquaintance sexual assault in adult males. References
