My boyfriend and i were fooling around last night. We were doing a couple of things before that but after that he took a shower. But later, we got into it again and well we were unprotected. Although he was at his recovery state and he wasn't able to get close to ejaculation or orgasm. He put it in because we were just trying it out and he went in and out like 4 times but very slowly. Do i have a very high chance of pregnancy?
