Painful Sex

Lisabet
So I've been expirencing painful sex for about a year and a half now. I hooked up with this girl and she cut me on the inside of my libia. I've been to at least five Gynos and they don't see any scars or cuts. Sometimes it's too painful to even have sex, and I'm scared to even try. What should I do? I'm scared my boyfriend will leave me because we don't have sex as much..
