Contary to the impression one can derive from the large amount of mass media discussion, sex education is generally still not an integral part of the school curriculum. One of several important reasons for this state of affairs is that adolescents are usually not represented in discussions of the need for sex education. Even when sex education programs do manage to become operational, the lack of teen input often results in such flaws as (1) having sexual physiology taught without being related to the psychosocial aspects of human sexuality, (2) avoiding controversial topics adults are uncomfortable discussing, and (3) conducting separate classes for males and females. The consequences of limited sex education are unwanted pregnancies and an epidemic level of venereal disease, along with ignorance and misinformation about sex which worries teenagers themselves. Teen input can help overcome such deficiencies. Adolescent representation in the planning and operation of a teen contraception clinic is also useful. Teen input insures that users of the service will not feel alienated by the program and contributes to teenagers' maturity by teaching them how to handle responsibility. (Author/CD)
