After years of dealing with shaking urine all over the bathroom and dribbling urine staining my underwear, I finally discovered a simple way to avoid the whole problem. After urinating, I stand over the toilet and run my finger along my perineum from just above the anus to the base of the scrotum. It is kind of like "milking" the urethra. All the urine that is usually stuck in it comes right out. I wish I had know about this 10 years ago - it would have saved a lot of mess.
