So my boyfriend snuck in my room last night and one thing led to another and we were naked in my bed. We're both virgins, I'm 15 and he's 16. We did do oral sex on each other and since he didn't have a condom, we had to grind on each other. I felt semen at the top of his penis before we did it but no penetration happened. So is it possible that I could get pregnant when he rubbed his penis on my vagina? I'm really scared and I don't want a child right now!
