Me and my boyfriend were kind of fooling around, pleasing each other, both virgins, but we were both really curious and we decided to make our genitals "meet", so the tip of his penis entered into my vagina for 2-5 seconds. I wanted to mention that I don't think that there was any pre-cm (he didn't ejaculate for sure), and he peed minutes before this happened. Am I likely to be pregnant?
