This report addresses several aspects of adolescent sexuality. An assessment of sex education in schools is provided: the sexual behaviors of adolescents are examined, including the age of first sexual intercourse, their attitudes toward masturbation and homosexuality, and their contraceptive practices (survey by OK Magazine and IRMA conducted by H. Léridou of INED and Dr. Elia of MNEF). The experience of a family planning center in the Val d'Oise (sex education through drawing) is presented. Finally, a discussion on the impact of AIDS on individuals’ sexual behavior (1988 CFES study).
