Most places teach what sex is and what the sex organs are, you’re exaggerating, even the most conservative places do this. I dont think the problem is just abstinence only programs, i feel like some schools lack teaching kids how to think about sex, understand sexual abuse and manipulation. We shouldn’t teach teens abstinence only, but instead teach them just facts about sex, casual sex still has it’s pros and cons we can’t act like sex is evil in nature or pure and that casual sex has no negatives.

Also i feel like a lot of sex is taught socially and different times and cultures change their ideas of sex and it’s specifics, I dont think there’s this one way to teach sex ed,
