Having to pee during sex?

Lupita • Violinist
My boyfriend and I were just now having sex and he was doing really good and I had came a few times, then I had this feeling to pee VERY BADLY. If he hadn't stopped I probably would've peed all over him. I'm confused why that happened, it was so sudden and it really had to come out. After we finished I told him and went to pee and I peed a lot.
