In the U.S. we do absolutely nothing with people that are attracted to other people regardless of what their age is. A person can potentially be as attracted as they want to a child, a teen, or an adult. Society and the law only gets involved that action is expressed. Simple attraction is not enough to cause trouble, there must be actions involved.
I suspect the majority of sex offenders in the U.S. are not paedophiles. I have no doubt that many are, but I think the majority are not. My understanding that the strong punitive measures against sex offenders are more of a testament as to how they largely cannot be rehabilitated, not out of revulsion for who they are attracted to.
