@xianc78 I'd rather not, tbh.
This reminds me of an episode of "Biggest Problem in the Universe" where Maddox tells the time he covered his dick while peeing as you'd do a hose to make it reach further and felt a "strange" sensation. Someone told him that was him forcing his pee back up the kidneys.
Don't know if that's a real anecdote, as he told it; but the thought is enough to cringe over.
