From people I know they also use them as toilet paper in cases where one is raw or otherwise sore. A bidet (or bidet seat in cases where that's not possible) would solve that problem outright.
It's amazing to what one can get used to. My washlet has a heated seat, now regular seats feel very cold.
Do you simply not know how to wipe your bum properly? My two-year-old has the basics of it, even if he hasn't quite got his technique down yet.
It’s also worse if you spend significant time using a bidet, then find yourself without one.
Ouch.
