Abstain, Be faithful, use a Condom, also known as the ABC model, abstinence-plus sex education, and abstinence-based sex education, is a form of sexuality education which builds on the abstinence-only model by recognizing that many (young) people do have sex outside of marriage. It also contains information about sexual and reproductive health. ABC still teaches abstinence as the best way of preventing unwanted pregnancies and STI’s (A), and stresses having only a single long-term sexual partner (B), but also includes information on safer sex practices (C). For this reason it is often seen as a compromise between abstinence-only education and comprehensive sexuality education. ABC programs can include issues of human relationships, the basic biology of human reproduction, safer sex practices and contraceptives, HIV/AIDS information, and masturbation.
