All Facts About Sex Education In the World

* Only 22 states and the District of Columbia require that public schools teach sex education.

The requirements vary from state-to-state — 19 states require the curriculum be "medically accurate," which typically means using clinical terminology for reproductive parts, and disclosing the mechanics of different types of sex. In addition, 33 states also mandate HIV/AIDS education, and 35 states let parents opt out on behalf of their child.

* Taxpayer money has been funding abstinence-only-until-marriage education since the Reagan era.

In 1981, Congress passed the Adolescent Family Life Act "AFLA" without hearings or floor votes. It was tacked on to another health bill, and the language outlined its mission: to "promote chastity and self-discipline." AFLA received the most funding of any sexual health program — $200 million in all — before the Obama administration ended it in 2010.

The Title V abstinence-only program, which passed in 1996 as part of welfare reform, is the only federal funding system left dedicated to abstinence-only-until-marriage programs. Every state but California has received its funds, which can be allocated to public and private schools, as well as community and religious organizations providing sex education. Those receiving the funds must adhere to a strict narrative when teaching sex ed, such as:

- Sex outside of marriage will damage your physical and mental health

- Abstinence is the only way to avoid getting pregnant or contracting an STI

* Gender discrimination is often a part of abstinence-only education.

Mississippi is one of the states with abstinence-plus curriculum. One of its school districts recently came under fire for comparing young girls who have had sex before marriage to a piece of used, dirty chocolate. The lesson adopted by the school district in Oxford had students unwrap a peppermint patty, then pass it around class and pay attention to how dirty it became.

This is demoralizing, but nothing new. In 2012, parents and physicians brought a lawsuit against the Clovis Unified School District in California for its inaccurate and biased sex education, which lacked any information on preventing STIs and pregnancy other than abstinence (a violation of California law), and included a video that compared a woman who was not a virgin to a dirty shoe.
