My boyfriend and I had sex tonight. It was the first time for both of us and while it was happening, the condom kept slipping off and getting stuck half way in my vagina. It scared me at first and he assured me that it was going to be okay. So it slipped off quite a few times and we re-adjusted it every time it came off. He did not ejaculate in me because he wanted to make sure none of it would get in me. But I m afraid some of the pre-cum may have gotten inside me. And I m expecting my period within the next few days. Is there a chance I could be pregnant? Also, could I get pregnant from us rubbing our genitals on each others?
