Ok, this problems concerns my wife to be. Every time we have sex, and she cums (very few times it happens just as soon as she feels she's about to cum) she feels the urge to urinate. This is especially bad just after she cums, to the point that if we dont cum at the same time, she has to run to the toilet and urinate, which takes a long time and sometimes it's really very little. this never happens to her when we are not having sex, and she's perfectly healthy otherwise. Any ideas?
