Don't be so sure you gun-toting slut!
Hmm...
I'll be the first to admit that I'm hypocritical in my attitudes towards sex and violence. I really don't think violence on tv and such is really all that harmful. Only in that people are taught at a really young age that violence is not the way to resolve conflicts and so they can clearly see violence in films, tv and video games as something unrealistic. Not so much with sex. Particularly in the States where sex is not discussed at all in the classroom or at least the best thing they can preach is abstinence (good luck with all that!), it would very difficult for people to see what can be expected and what cannot usually be excepted from sex.
This may be completely different from how sex is taught in Europe. So my observations are just limited to countries with no sex education.
Maybe just letting adults only is a little too restricting. But I still stand by that children should learn about sex in a more appropriate setting first.
