If I have been holding for ages, then evenif I feel that I am going to burst, I just end up dripping for a solid 5 minutes before I manage to let out a small stream that goes on forever at a very pathetic speed. It only becomes faster when I'm not feeling as full anymore.
My gf is the exact opposite, she starts gushing an incredible amount of pee, when she is desperate to go. Infact we joke about how the strength of her stream then is probably strong enough to cut glass haha
