No, I have no kids. I’m not sure what you mean by “used to be,” but all of these things were covered by my 7th grade health class in the mid 90’s, and there were kids (not me, I was a late bloomer by choice) in that class that had engaged in each and every one of the acts listed on this sheet of paper, some of them 2-3 years prior. Kids that young should not be having sex, full stop. But they do. They have for at least 10,000 years, and no amount of parental hand-wringing has ever stopped it. And if you attempt to leave education to the parents, most won’t bother out of anxiety, embarrassment, or not knowing enough themselves to be accurate and mature about it ('twas ever thus). And kids are more likely to listen if they hear the facts from multiple sources, anyway. They’ve definitely got multiple sources pushing them in the other direction.
Maybe you just want to remove oral and anal sex from the list (these seem likely to be the most problematic for many)? Guess what, you’ve just excluded all the gay students. You didn’t have openly gay students in your middle school? I did. And others we all had guessed that didn’t realize or admit it until much later. But lack of understanding of the risks and safe practices for these kinds of sex causes serious harm every day to straight and gay students alike.
