Among men who have sex with men (MSM), the decision to use a condom was influenced by multiple factors, according to a new study by researchers at George Mason University (GMU) in Virginia and at Indiana University. According to a GMU statement, the study questioned nearly 15,000 participants about the last time they had anal sex. While only one out of three incidents of anal intercourse between MSM was condom-protected, only 2.5 percent reported that he or his partner had ejaculated inside the other without a condom. Among other findings, the study shows that men ages 18 to 24 were more likely than other age groups to use condoms; that black, Latino and Asian men reported condom use more often than whites; that men in a relationship were less likely to use condoms than those who were not; and that men used condoms most often in a sexual partner's home or in a hotel or motel, as opposed to a car or van.
