text: I would say it is not common for woman to urinate during a climax. What you might think is urination, could be an orgasm. Some females will squirt during their orgasm, but this is usually about 5-10 ml. Some maybe a little more, but not much. If you are passing more than say a big table spoon then you need to go and get checked out by your doctor. \n\nWeak bladder can cause this, but like I said, its not common. Hope this helps out, kind of hard to diagnose over the Internet cause lab tests and exams are a key part of it.
