I lost my virginity to my boyfriend and there was no pain and only a little blood. But last night we had sex for the second and third time. Both times it didn't hurt at first. But then when we were in certain positions or he put it in a certain way, it felt really deep and there was like a sharp pain. And both times I bled a lot (more than the first time).

Is this normal and I just need to get used to it? Or could there be something wrong?
