Few studies survey men who have remained undetected after engaging in acts of sexual aggression against women. Most survey women who were targets of sexual aggression or else survey men who consent to being identified. Using anonymous surveys of 2,689 U.S. and Canadian men (18–34 years), we aimed to assess rates of self-reported sexual aggression, reports of strategy effectiveness at forcing known reluctant women into sex, and men’s views of the circumstances, motivations, and positive and negative outcomes. Men reported occasions where they tried to get a woman to engage in sex that they knew she did not want and to which she had not consented. The women were individuals with whom the men shared no prior romantic or sexual history. Overall, 95.1% reported having recently used at least one of the strategies to get a woman to have sex who they knew did not want sex and had not consented. Most of these occasions (65%) resulted in successfully forcing the woman into sex. All of the 36 strategies generated from formative work were reported by at least some men; the average number ever used was 8.94. Consistent physical pressure and verbal coercion were common; overt force, including physical restraint and use of pain, was less common but not uncommon. Men who viewed themselves as better than same-aged male peers “at getting what they want sexually from women” used more forceful strategies. The men persisted for many reasons, most often because they were horny (38%) or because the opportunity arose (28%). They reported many positive outcomes from these interactions; most (70%) perceived no negative outcomes. Using anonymous survey methods provides a novel channel to capture men’s reports of the factors scaffolding their use of sexual aggression. Implications for prevention and making long overdue inroads into reducing rates are discussed.
