My boyfriend and I didn't have sex at all. We were fooling around and what not, and we got fully naked and had oral sex. We then felt like we wanted to go on farther and we did. I was on top of him and he and I were rubbing/pushing/grinding without any clothes. He never got inside of me, because he was too big, but he did try. It just didn't work. Is there a chance I could be pregnant? He never ejaculated during or after, he also said he doesn't think he pre-came. Is there a chance I'm pregnant?
