Cartoon Network not for kids

I know the Cartoon Network has programming geared towards adults, but that's not what caught my attention the other day. I'll admit to being pretty slack about letting Desmond watch shows that maybe aren't the greatest thing in the world for a 3 year old, but at least they are geared towards a young audience. However, I've seen an ad on there recently for kids to talk to their parents about sex and take control of their bodies. He usually tells me he wants whatever they are advertising during the cartoons, but if he asks me to talk about sex before he turns 4, I don't think I'll be able to take it.
