Question about underwear "ritual" as a child?

My son was doing something similar. He was molested when he was 3yrs old he's 10 now. I took him to a psychiatrist. He finally told us he liked what he was doing cause it felt good.Well,as far as I know he stopped. I don't know if he'll be gay or not I really could care less,I'll still love him. I was more concerned with him hurting himself. Do u still do it if not maybe it was just a habit don't worry about it believe it or not I think just about everyone at that age does something weird. It's sounds like your really stressed-out over all this. If I were u I would seek some help and talk to someone about how u feel,someone that will keep it confidential , it will make prob. make u feel better to let it out with out being criticized. Good Luck!
