From what my recruiter has told me, every time they stopped in port, they were showed videos on what STD's look like...so I think I'm going to get one hellava sexual education once I hit a command that's going to be travelling around the world....

as for what was taught it in school... it was mainly, this is a p***s, it's got these tubes that do this and that. One kid raised his hand and asked the teacher "So when are we going to learn about the girl's body parts?" I forget what happened after that
