My school had no sex ed. At all. Most of the students werent sexually active, but those of us that were, myself included, took it upon ourselves to make sure we took care of each other. You see someone that looks like they might want to do it, you pull em aside, say hey, make sure either you/your partner wraps it up, its cool if youre not straight etc. We all knew that the school wouldn't cover any of it, so we did our best to help a brother/sister out.
