I don't know about where you live but essentially we had no sex education in Scranton Pennsylvania public schools. I live in Nebraska now and the public school in the town where I live has a good sex education program. Today's kids are much luckier, if they are given all the information they need they will hopefully make the right decisions for them.You just said something, but you said nothing at all.
How did sex education 50 years ago make kids unsafe and uninformed?
It seems like you have a belief that you don't want to say out loud.
