About Your Sexuality, or AYS, was a comprehensive sex education course published by the Unitarian Universalist Association in 1970, with further revisions in 1973, 1978 and 1983.[1] The course materials were originally developed by Deryck Calderwood. Although made available to other organizations, the materials were primarily used in courses taught to youth ages 12–14 (in mixed-gender groups) in Unitarian Universalist congregations.
AYS covered many topics including anatomy, gender identity, relationships, sexual intercourse and intimacy; as well as covering sexually transmitted diseases and birth control. AYS was based on the assumption that sexuality is a natural and healthy part of being a human. It considered the wide range of sexual feelings and behaviors as normal. AYS was unique among sex education courses because it used visual materials that depicted human sexuality in a realistic and graphic fashion. For example, film strips used in the course showed images of real heterosexual and homosexual encounters, and masturbation.[2] Other media used in the course of AYS included audio tapes of interviews with transgender, homosexual, and heterosexual men and women speaking about their sexuality.
