>>41226006I have a vagina so I will try to explain the phenomenon I think she's talking about. When you have a cunt you can contract said cunt to push more urine out. If you do this enough times you can effectively empty your bladder, but it's a really uncomfortable feeling that gives you the overwhelming sensation that you need to piss even when you don't. So you run back to the toilet and push, but this only exacerbates the problem. So you just have to lie there in discomfort for hours until the feeling fades.
Hope that helps your masturbation fantasies.
