In my times, when there was no such thing avaliable as internet, we kids used to smuggle and struggle for prOn. And I'd let my kids to watch whatever they want. Heck, I even talked about sex with my friends daughter! It was more difficult than I thought, mostly becasue she is a girl. But when I talked about sex with my brother (now 13 y.o.) we used to laugh to tears when talking serious and then reading euphemisms about masturbation and onther sexual topics.
So I wouldn't see anything wrong in reccomending this site to any of my kids or other minors. Today's morality is sick, people need to be more open minded about their sexuality. I'd rather see some consensual sex and nudity in cartoons than violence.
