Well, I have one of the simple unheated hose sprayer-type bidet things which I installed during a period of let's just say discomfort at some point in the past, and that's what I do, but I assumed the hardcore bidet users had some superior solution, like mentioned below.
The higher end models have heated blowers. But TP is kind of superior to that imo.
Small towel. Bath towel > Face towel > Foot towel.
(Spot the euphemism. But it is also used for drying feet, after wrapping the body with the bath towel, when coming out of the shower.)
