My boyfriend and I engage in sexual activity but we haven't had any real sexual intercourse yet, just you know, mutual masturbation, that sort of thing. During one such incident, I bled quite a lot from my crotch. At first I thought my period had come (as I've been feeling hornier the last couple of days, it's generally like that just before my period) and put a pad on, but I noticed that I didn't bleed very much after that. Even the next morning the pad was not very stained.

I'm guessing my hymen broke or something but I had thought there would be some pain and there was none at all..?

Any help would be appreciated, thank you!
