I've started having sex w strangers all the time. i hate it but can't stop myself. what's wrong w me?

Therapy may help: you need to have some talk therapy going to help you with this dilemma. There can be a lot of reasons for how this satisfies you and drive you. A qualified psychiatrist or psychologist should be able to help you understand why this is happening

Get help: So many factors to consider for your behavior which is high-risk and impulsive. Does anyone know where you are when you go off with a stranger? You'd do well with support and therapy. See your pcp to ask for referral to a mental health professional. Don't be embarrassed. You want help and that's a good thing. Be safe. Hope this helps.
