The article is pretty hilarious, but honestly it sounds like the guy actually needed help, and shit himself on a previous flight. This is literally the most basic assistance ever for any CNA or nurse. Acting like she was abused or couldn't rid herself of his scent is pretty ridiculous, so it's kind of hard for me to trust the rest of the account of it "ohhhh deeper." Like, maybe she barely touched him and he genuinely just needed to wipe his ass lol. I have a hard time believing it was some sexual thing.
At the end of the day, it sounds like he was being rude and she could have refused to do it. He would have shit his pants and urinated on the floor, as he said.
I'm a little surprised this kind of thing hasn't come up a lot more frequently, especially on long international flights.
