unknown and seriously need help. I'm so scared :(

I went out on a date today with a guy I've been talking to for a while now. We have so much in common and enjoy being around each other and well today..... He bent me over and we had sex for like 2 mins because it's been so long for both of us and he was going to come to soon so he pulled out. Well needless to say now I'm bleeding and I can't figure out where from my vagina it's coming from. Is it possible I tore something? I can't see any tears help?
