I had surgery what required catheterization a few times. Last time, the catheter bubble failed to deflate properly. It was... Unpleasant. Got stuck. Thanks for the nostalgia!
I've been aware of the phenomenon for years. And no I have no desire to look at pictures of such things. I just don't get it. Why? And again all I ask and all I want to know is that's a very small exit-only hole, why/how do people put things up there?
