Pain & Bleeding After Sex?

I recently started having sex with this guy. I am very kinky minded and love it rough. I have never met a man able or willing to push me to my limits until now. We literally had sex for 5 hours the first time. Then the next morning sex for another 2 hours. It was very rough. The next day I started noticing blood and experiencing pain near my cervix. I have had issues with vaginas dryness, so I am wondering if that could have caused a tear or something? It’s been 5 days. We had sex once two days ago but I bled so much afterwards it was like my period. He refuses to have sex because he doesn’t want to hurt me. I don’t blame him. Have any of you experienced anything similar?
