Sexual assault remains an important public health issue due to the violence involved as well as the potential for health risks such as sexually transmitted infections. Alcohol has been associated with both violent and risky sexual behavior. This study assessed the frequency of sexual assault perpetration, alcohol use, and condom use during sexual assault in a community sample of young, heterosexual male social drinkers. Participants completed measures of their sexual assault perpetration. More than 50% reported sexual assault perpetration; 60% of these reported repeat perpetration. Almost one half of perpetrators reported alcohol consumption prior to every sexual assault incident. Never having used a condom during penetrative sexually aggressive acts was reported by 41.2% of perpetrators. Alcohol use and condom nonuse were positively correlated for acts of forcible rape. Findings provide information about the infrequent use of condoms during sexual assault incidents and support prior evidence of the association between alcohol and sexual assault.
