Felt like I ripped last night? TMI

Hi all. Last night my boyfriend and I were having sex, we went for round 2 and I was on top when all of a sudden it felt like he bent in half and I just felt something rip, tear or explode. It was really painful for 10 seconds then it got better so I kept pushing on lol

Then 15 minutes later we stop and find blood all over us. Like... ALL. OVER. He’s the best and was like it’s okay it’s okay don’t worry about it! But I was horrified by the amount of blood that was on him and me... Now it’s the morning after and I’m still bleeding but it’s not heavy, and I had a few clot tissue kinda thing... What could have happened?
