Did I pee myself or orgasm??

Okay so my and my bf had some really bomb ass sex. He’s been gone for work and after a few weeks away came to see me basically cause we both wanted sex before he left again. We were in the middle of things and he changed the position and it hit in a way it’s never hit before. I was seeing stars and was hella into it. All of a sudden I felt like I peed myself and it wouldn’t stop... Then he got hella turned on by it and then finished.

Wtf happened and is this normal?? I remember it happening to me one other time with a different partner but it was NOTHING like this.. like it felt great but I genuinely thought I peed... HELP.
