Kids may seem like they can have sex at 15 and younger, but physically, females may not be developed enough. Sure, I had sex when I was 12. But I HAD NO IDEA what I was doing. I knew I could get pregnant, but I really didn't understand the ramifications that would have come with getting pregnant. I didn't understand what exactly AIDS was and how one little accident can cost you your life.
Sex is way out of hand in our society.
And I think that the net and all the pr0n available doesn't help matters. If you wanna help fight perverts online, especially to protect children, then report child pornography when you hear about it or see it. Sites like Condemned.org and ACPO.org can take care of it from there. I hate to say it but online sexual propositions probably do less harm to children than tv and movies. That's just my unrealistic answer.
