When the last part of my pee comes out it starts spraying everywhere, it happens almost every time it doesn't spray until I'm almost done why?

Here are some... The very end part of urethra is called fossa navicularis, which is round with even diameter (but in oval ellipsoid shape) like an adjustable nozzle of garden hose, from which the configurating and shaping of water flow widely vary depending on the water pressure. So, at the beginning, urine flow is straight; toward the ending, it slowly becomes spraying or splaying. More? Ask urologist...
