When I had my first sex ed class I think I was in 4th grade then we had one in 6th then 7th grade. Each went a little bit more in detail then the last. Then my junior year we had health independant living which showed us how to live on our own from keeping a check book to carring for a child. You couldn't graduate unless you took the class. So I wouldn't say all of americas school systems don't teach you anything. Oh wait that's about all they taught us. So basically in other schools where there sex ed sucks my school had a good sex ed program but crappy everything else
