EDIT!! How much should schools teach in sex ed?

My school only taught us about aids. That's it. We have the highest teenage pregnancy rates in our state (hmm wonder why 😒). Question is how much should the schools teach kids? It's up to the parents for the most part but most parents won't have that talk with their kids. I just see a lot of women make the same comment about sex ed and they seem to not realize most schools won't teach it. And some girls can't talk to their parents about it. But if schools did step up and say hey we are going to do this right what do you think should all be covered?
