I am sorry. I didn't mean to be flippant. I had no idea that was a thing and reacted in the moment. Are you ok? Is your penis ok? Can you teach me your ways, senpai?
Ok, I've had many catheters inserted into my penis, I've just never had an expulsion of air. Usually getting it put in wasn't a big deal, as I was always incoherent or unconscious, but getting it taken out was cathartic and unpleasant.
I said something irredeemably stupid as it's clear I didn't actually read the last sentence of your original post. I apologize for wasting your time. That said, do you have any pictures?
