Hello, I Am Very Concerned About My Situation Because I've

Hello, I am very concerned about my situation because I've never seen anything like it. I am with my current boyfriend which at the time we haven't been able to have sex because when we begin I get so extremely wet that his penis slips out and we can no longer continue. He is the only guys this has happened with. It is the same situation every time. He says this only happens to him with me. What should I do?
