Once you've gotten used to using flowing water to clean yourself, going back to a place where there are no bidets (or equivalent middle-east style handheld toilet shower) and you can use toilet paper only feels like the grossest/nastiest thing.
I heard someone explain it like this: "Imagine you got some shit on your hand, how would you clean it? Well you'd go to a sink and wash it off with soap and water, you wouldn't just wipe it off with some paper towels. Ok, so why do we do that with our asses?"
