The development of hymen in different animals is different, so the following is an introduction to the development of hymen in humans.

"It is well known that the hymen at the vaginal opening of a woman's vagina will rupture after the marriage. The urethral orifice is pulled or deformed, or blocked below the urethral orifice, blocking the way out of the urine under the urethral orifice like a "threshold", then it means that she has hymen umbrella disease. Don't underestimate such a small piece of broken hymen. It It can cause bad irritation to the urethra and cause urination at all times.
