The most recent data suggest that between 60 percent and 80 percent of North American college students have had some sort of hook-up experience.
Similarly, in a study of 832 college students, 26 percent of women and 50 percent of men reported feeling positive after a hookup, and 49 percent of women and 26 percent of men reported a negative reaction (the remainders for each sex had a mix of both positive and negative reactions; Owen et al., 2010).
On average, both men and women appear to have higher positive affect than negative affect after a hookup.
In one study, among participants who were asked to characterize the morning after a hookup, 82 percent of men and 57 percent of women were generally glad they had done it (Garcia & Reiber, 2008).
Although much of the current research has been done on college campuses, among younger adolescents, 70 percent of sexually active 12- to 21-year-olds reported having had uncommitted sex within the last year (Grello et al., 2003).
Similarly, in a sample of seventh, ninth and 11th graders, 32 percent of participants had experienced sexual intercourse and 61 percent of sexually experienced teenagers reported a sexual encounter outside a dating relationship; this represents approximately one-fifth of the entire sample (Manning et al., 2006).
