Hookups are becoming more engrained in popular culture, reflecting both evolved sexual predilections and changing social and sexual scripts.
Hook-up activities may include a wide range of sexual behaviors, such as kissing, oral sex and penetrative intercourse.
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).
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.
