I don't have any answers that address lowering the percentage of children exposed to sexual violence, but let's think on it, and perhaps, collectively, we can come to some resolution. When I was 17 I had been having sex since I was 10. I think that if they are under 15 with consent it should be stat rape. They try kids younger than that for murder as an adult. My reason for the stat rape rant is that when I was 19, my girlfriend was 16.
Violence begets violence.
For children to experience less violence those around them must experience less. As for cheating stripper chicks, when I was 16 I'd love to have know one. I'm thirty and still counting times on both hands. I've been beaten, tied up with barbed wire, set on fire and been through various things painful and spurious. If you think castrating is going to limit sexual behavior like pain did for me because it is going to hurt when they cut his balls off, you have another thing coming, because they give them anesthetics when they do it.
