Bleed During Sex

A while ago I had sex and when we were finished there was a lot of blood on the sheets, he thought he had 'popped my cherry' but I had sex before him and that never happened, I've never bled during sex before. I wasn't on my period and wasn't due to have my period and I didn't bleed after sex. I haven't had sex since because I'm terrified of bleeding again and feeling embarrassed, although I'm not in a relationship at the moment there may come a time when I will be and I'm scared to have sex with that person. Also, I should note he was extremely rough. Any ideas of what I should do? Or if I should wait until I'm in a relationship and get checked then?
