If the school system was really about teaching people things they need to know, sex ed wouldn't be a part of High School. Between parents, WebMD, Teen Vogue and PornHub, kids are already gonna figure out how to have sex and probably are gonna be doing it. The only goal I see of sex ed is to make sure the kid knows how to kill a baby so they can stay in school.
