I personally don't understand the difference between an adult who has anxious impulses to touch children and teenagers who have anxious impulses. If the teen isn't treated isnt it likely to go into adulthood? Yes they should have better decision making skills but I dont personally think they say hey I really want to touch that kid to get some sexual gratification. At least that's never been the case with me but I suppose for some it is the case. Maybe I have a impulse control problem but manage it well.
