I don’t think that trying to relate to others and look for coping tips is reassurance-seeking. I’m sorry you’re going through this :(
The more you try to not do something the more you are going to want to do it. I have read that the important thing to do here is to not try to prevent anything from happening. Thoughts urges feelings. This doesn’t mean act on them but trying to prevent them makes it a much more important thing to your mind. You’re sending a danger signal
The best way to deal with it is to accept and feel uncertainty. “Maybe I’ll stare at this person’s crotch, maybe I won’t. Maybe that makes me a weird person, maybe it doesn’t. Can’t know for sure.” And just experience the unpleasantness of thinking that. Doesn’t mean you go out of your way to not stare at people but it does mean that you don’t try overly hard to stop it either.
