Research examining oral sex during adolescence tends to investigate only potential negative consequences without considering its place in sexual development or distinctions between cunnilingus and fellatio. Using retrospective reports from 418 undergraduate women, we examined the relations among young women's ages of initiation of both cunnilingus and fellatio and sexual motives, experiences of sexual coercion, and indicators of psychological functioning. Age at cunnilingus initiation was unrelated to sexual coercion or psychological functioning; however it was related to engaging in sex for personal stimulation and gratification ("personal drive motive") and to feel agentic, assertive, and skillful ("power motive"). Age at fellatio initiation was related to feelings of inferiority compared to others and a devaluing of the self ("interpersonal sensitivity"). Findings challenge the unilateral assumption that all adolescent sexual activity is negative and indicate the need for future research distinguishing between cunnilingus and fellatio.
