AITAH for having so much sex with my bf, that he bled?

I (20F), was enjoying the long weekend with my boyfriend (21M). We had sex 10 times in one day. I knew he was getting sore, but we both kept going, because we were both still willing to, and I thought we were the same level of sore. Then when he went to pee there was a little blood and I felt awful. He tells me it's okay, and he was willing to continue even though he was bleeding. But we went to urgent care and they said everything was okay. I still feel bad even though he's reassuring me it's fine. AITAH?
