Bleeding ALOT during sex.

2 weeks ago I lost my virginity. The first time I did it I bled a lot to the point where we had to stop. I just thought it was “popping my cherry” this Friday I had sex again I bled a lot again! Mind you my bf didn’t get mad he was very understanding and we took a shower together. Today I had sex and I bled a lot and It’s just frustrating because I don’t know why. It’s just a lot of blood I can’t tell when it comes and it doesn’t hurt just very frustrating and alarming. Mind you I was a Virgin before all this started happening so it can’t be no type of disease.
