"Just before I went in for my job interview, I made a pee-emptive strike so I wouldn't be squirming in my chair answering questions. Glad I made that move as I ended up needing to poop!"
"I didn't want to wake up in the middle of the night to take a wizz so, as tired as I was, I took some time to make a pee-emptive strike before going to sleep."
One's prostate gland reacting to someone's descriptions of painful experiences, or a reaction to the sight of someone elses painful experience. This is a dull, almost tingly sensation that lasts a few seconds and then disappears into the ether. Depending on the duration and magnitude of the sensation, this could be the equivalent of your prostate crying uncontrollably, or just emitting a concerned sigh.
My wife told me about her mom's varicose vein surgury, and I almost doubled-over from prostateempathy.
