I had read that when the prostate is removed, the urethra becomes shorter. One of two things happens: the bladder is pulled down or the penis is pulled in. I guess I’d rather have my bladder stay where it is. I had RP in November and my penis has shrunk. I have to lean over the toilet so I don’t pee on my clothes. Holding it becomes more of a science. It’s functioning fine(knock on wood-no pun intended). Hope this helps.
