I bled everywhere on him 🙄 and he was okay with it?

So I have a story to tell y'all 😩

My s/o and I work at the same place, so whenever we go on break at the same time, it's common we will sneak away and have a little play time at his place before coming back to work. We just recently started having sex, and this time it was great. He was rough, and when I say rough, I mean ROUGH. We were switching positions, and he stops me and says "just so you know, there's blood everywhere." I know he was trying not to freak me out, but I look down, and there's literally blood EVERYWHERE. All over me, all over him. We stop, of course, and go shower and clean up. Now he has blood stains on his mattress. This wasn't just like, period blood. This was literally actual blood, like coming from a wound. There was so much of it. He was cool about it, thank god, but I'm still a little shaken by it. I'm not bleeding anymore, and I read that sometimes when you get a little rough, your cervix can bleed because the blood vessels are easily broken. Has anyone ever had this happen to them? I just need to know I'm not alone 😅
