how come every time after i masturbate i got to urinate?

I urinate post intercourse every time! It makes me have to go, sometimes i will get the urge during sex and i will go a couple extra rounds, reason being the prostate and the bladder are right on top of each other. when one becomes excited or full it irritates the other.

Human nature my friend, nothing to be worried about!

18 hours and no reply huh? I'm a girl and the same thing happens to me I just never thought to question it. I check yahoo, and med.help had a reply for you hope it helps, even if it was a girl who answered, hope it helps.
