I have a similar issue but am much younger. I think it is about total parent (mom) rebellion. But it is becoming obsessive. I feel like I need the sex and that a little bit frightens me. Most of my girlfriends struggle to have an orgasm and I can so easily have one. If I cannot find some guy to have sex with I will rub against the sofa arm when no-one is home in order to relive the urge. I think I need some sort of medicine.
