Pain or Bleeding

I worked in a party resort over the summer months and as you can imagine there was a lot of sex, which I'm not ashamed of, nobody should be slut shamed. However more times than not I would bleed during/after sex, it was humiliating! When I say bleeding I don't mean a bit of spotting either, it was as though my cherry was being popped every time, like a really heavy period. I also experience pain in certain positions when the guy goes too deep...I was wondering if the bleeding could be something to do with my pill, as I've been checked by the doctor and I haven't got any STIs, but yeah I'm slightly worried, has anyone experienced anything like this at all? HELP 😭😭😭😭
