Prostate Stimulation (Help Please!)

[Experimental2402]

I was experimenting with my girlfriend last night and we'd thought that we would try anal stimulation. When my girlfriend found my prostate and started to stimulate it I couldnt help but get the urge to pee and I was forced to run to the toilet to save myself the embarrasment if I had pee'd on my girlfriend. Is this normal? or is there another reason why this is happening?

I myself have never felt that however, I know this is a common thing. My guess is because of the anatomy of your body, however you won't be peeing because your body has a valve that won't let you. I on the other felt the urge to do something quite nastier the first few times... but I got used to it and rarely/if ever feel it.
