boyfriend likes it when I pee?

Ok, so my boyfriend like to finger me right after I have an orgasm from him giving me oral. He stimulates my G spot and I freaking pee myself. I know it's not squirting, I don't get the "orgasm" feeling when it comes out. I just can't hold it in and I push it out. But he loves it. And he knows it's pee 😐
Wtf?
