You know you can wash your hands after right:) I get that lots of people use bidets but personally I find them confusing and gross. In any shared setting you've got a bunch of other people's ass water that's been sprayed around, plus a nozzle that gets God knows what sprayed on it, and even on my own I'd have no idea how to properly contain the water and get it to do what I want. Obviously there's a solution to that, but practically I don't see TP as an inferior alternative. Just my feelings as an ignorant westerner that's seen a lot of bidets and said no thanks.
