I agree your son should speak to a therapist. I'm sorry you're understandably upset. Do you have other children - I don't mean to worry you but I would be worried about him touching other people in your family, especially younger children...siblings or cousins. He needs to understand he needs permission before he touches anyone!! For now you should lock your door when you're sleeping. Has he expressed any homosexual tendencies? Ask him point blank ...why is he doing this.
