This show is great, I have only seen a few episodes, but Its enough to know what it is about. There is a little drama an some bad language that isn't appropriate but nothing major for youths. There is a lot of sex stuff in there, even an episode called sex ed but the sex stuff doesn't go farther then what you would learn in sex ed. Most twelve year olds would have gone through sex ed by now, Or at least would get the jokes. So for youths there really is not anything to worry about. Thats coming from a twelve year old (twelve is considered youth).
You can trust twelve and up with it.
