口交
Oral sex is also commonly used as a means of preserving virginity, especially among heterosexual pairings; this is sometimes termed "technical virginity" (which additionally includes anal sex, mutual masturbation and other non-penetrative sex acts, but excludes penile-vaginal sex). The concept of "technical virginity" or sexual abstinence through oral sex is particularly popular among teenagers. By contrast, lesbian pairings commonly consider oral sex or fingering as resulting in virginity loss, though definitions of virginity loss vary among lesbians as well.
