In the Amazon River there is a fish that may swim up your pee hole. It's not good---though a seeming rare event according to that wiki---but it's a risk I will never face because I won't dunk my junk in a Brazilian water course. But I do have a cat. Her dismount from my crotch involved a hind leg planting into my business and all I had down there were boxers. As she jumped off a claw flicked into my pee hole through the cloth.I yowled as any man would when a claw goes the wrong way up an exit only. The odds of it happening again are remote but it will prompt a precautionary re-arrange lest she hole in one again.The urethra; it's not for cats.
