The alcohol contexts of consent, wanted sex, sexual pleasure, and sexual assault: Results from a probability survey of undergraduate students.

OBJECTIVE: To examine, in a probability sample of undergraduate students, characteristics of students' most recent sexual experiences (including alcohol use) as well as their experiences with nonconsensual sex.

PARTICIPANTS: In January and February 2015, 22,046 students were invited to participate in an anonymous, cross-sectional, Internet-based survey; 7,032 surveys were completed (31.9%).

METHODS: Measures included background characteristics (age, gender, sexual orientation), most recent sexual event items (sexual pleasure, wantedness, alcohol use), and experiences with nonconsensual sex (since college and lifetime).

RESULTS: Respondents reporting sober consensual sex were more likely to report higher levels of sexual pleasure and wantedness. Nonconsensual oral, vaginal, or anal penetration occurring during college were reported by 15.8% of women and 7.7% of men. Students more often told friends, partners, or family members and rarely disclosed to university faculty or police.

CONCLUSIONS: Implications for campus policy and health education are addressed.
