Everything is said to be bigger in Texas, and that includes schools’ share of Federal abstinence-only education budget.

It also, according to RH Reality Check, includes teen pregnancies: one of the highest rates in the country, costing taxpayers more than $1 billion a year.

That’s because abstinence is the least effective form of birth control. While perfect use leads to a 0% failure rate, the mechanism—pure willpower—doesn’t lend itself to perfect use; many reports compound the problem by comparing perfect use of abstinence with typical use for all other forms of birth control.

Ab-only education seems to be predicated on the notion that sex is like any other engineering feat: if you don’t know about it, you can’t do it. You need to be taught at least some rudiments of architecture before you can build a skyscraper, and the same purportedly applies to sex. This is why neolithic humans didn’t have skyscrapers, or sex.

What kids are taught instead is arrant nonsense:

Sexually active teens are more likely to commit suicide; women who lubricate during sex are more likely to get pregnant; people who have sex before marriage are less able to be “intimate” later; “the divorce rate for two virgins who get married is less than 3%.”

Sex ed doesn’t need to be about the mechanics, but it is irresponsible not to teach students how to stay safe when they are drawn to doing it. Moral education is the responsibility of families; while the schools have a responsibility not to undermine that, they needn’t refrain from teaching students necessary information in the name of supporting it.
