Do you want porn, or do you want to create more closet pedophiles like half the Catholic clergy?
You can either tolerate human nature, which includes sexuality, sorry, or you can suppress it and break people to their cores, causing harm to them and eventually others including children.
Why is it, when we try to suppress parts of our nature through law, it's always lust and never the far more destructive greed? Lust can be positive and celebratory, greed has no redeeming qualities.
