virgin?

So my bf and I were making out in the car, and then he started to finger me, which I was okay with. He was asking me if he could try two fingers, and I said okay. It hurt but felt good, and he was really deep in me, but when I got home, I noticed I was bleeding quite a bit and the next couple of days my vagina hurt. Whenever I would walk or sit it would hurt. What does that mean?
