The sex education programs provide students with practical information, which one may apply for one's daily life, as well as the knowledge about the biological mechanism. (e.g., the risks relevant to sexually transmitted diseases, getting accidentally pregnant, and possibly having an abortion as a result, and about contraception, such as condoms or birth control pills.) After learning about the risks of having sexual intercourse, the teen may want to extend the initial sexual intercourse. Thus, sex education in public schools could affect an individual's perception towards teen-sex.
