The survey involved 477 undergraduate students, mostly white heterosexual females, enrolled in a human sexuality class. The majority (98%) of participants was age 24 or younger; the average age was 20.7 years.
The participants answered the following question:
"Would you say you 'had sex' with someone if the most intimate behavior you engaged in was ..."
• Penile-vaginal intercourse?
• Penile-anal intercourse?
• Oral contact with partner’s genitals?
• Partner’s oral contact with your genitals?
• Partner touches your genitals?
• You touch partner’s genitals?
• Oral contact with partner’s breasts/nipples?
• You touch partner’s breasts/nipples?
• Deep kissing?
• Partner’s oral contact with your breasts/nipples?
• Partner touches your breasts/nipples?
Among the survey’s notable findings:
• Only 20% of those surveyed said oral contact with their partner’s genitals would constitute sex. (or 80% don't believe that oral sex is having sex)
• Less than 80% of participants considered penile-anal intercourse as sex.
Males were much more likely than females to say sex included the following behaviors:
• Their partner touched their genitals (13% vs. 7%).
• Orally stimulating a partner’s breasts or nipples (9% vs. 4%).
• Touching a partner’s breast or nipples (8% vs. 3%).
