I have a pee fetish and my girlfriend is wonderful enough to oblige. She's peed on me a few times and we both think it's fun. But when I try to pee on her, even if I really have to go, I just can't. Then as soon as I'm on the toilet, I pee instantly. I have no trouble peeing in the bathroom when she's also there, it's just during sex I can't. I thought maybe it's because I have a boner, but even when I go soft it doesn't happen. I'll have a strong feeling that I need to go and I'll feel the pee coming almost there but I can never finish the job. Once I tried starting to pee in the bathroom, hold it, and then go to the bed and resume. Nope, that didn't work either.

Anyone know how to overcome pee shyness in bed? I hope eventually I can even pee with a boner because I want to pee inside my girlfriend at some point.
