During sex me and my gf had been going at it for a while, she kept telling me it felt really good, but she made me stop all of sudden because she felt like she had to pee, we talked about it more and she said it might have been an orgasm but shes not sure because shes never had one before, what is she feeling?
It's quite possible your girlfriend had what is referred to sometimes as a "g-spot" orgasm causing "female ejaculation". Many women report it feeling as if they had to pee suddenly.
