Like... who doesn’t already?
That’s the reason my wife won’t shower with me! hehe
There are some things for which men simply don’t need instruction or direction. Unless they like the sound of “Eeeyeww!!” they just can’t ever let the wife or girlfriend know.
I recall a study done in the U.S. several years ago. I believe that they determined about 75% of men pee’d in the shower.
I addition to peeing in the shower, some admitted to peeing in the pool, too.
Heck, I don know a man who won’t pee anywhere! As an Army BRAT, i think it was expected!
