First of all, sorry about the subject of my message, haha, i don't know the scientific term for this condition. I'm a girl, so it's a little bit embarassing. Every time i pee, i would pee alot, but then after i finished, i would sit for one or two minute and i suddenly felt another urge to pee again. So it's like i have to pee for two times before i completely empty my bladder. Is it dangerous? Well, it doesn't happen all the time, but most of the time.
