This study presented and tested a model of sexual satisfaction for late adolescent girls. In this model, sexual self-concept and approach sexual motives were tested as predictors of adolescent girls' sexual satisfaction with their most recent experience of sexual intercourse. A total of 116 girls in 12th grade (ages 16-19) completed measures of sexual self-concept and sexual experiences. A smaller number of girls (n = 70) with intercourse experience completed measures of their motives for engaging in sex and their sexual satisfaction with their most recent intercourse experience. Results showed that both sexual self-concept and approach sexual motives were associated with greater sexual experience across a broad range of sexual behaviors. Furthermore, sexual self-concept and approach sex motives predicted higher sexual satisfaction at most recent intercourse. The importance of investigating positive factors in girls' developing sexuality is discussed. (Contains 1 table and 1 figure.)
