In East Africa, squat toilets are the norm, in most smaller towns. When I rode the rails, from Mombasa to Nairobi, there were two toilet options: On one side of the car was a Western style toilet and toilet paper, on the other, a steel plate with a hole and a nice hose you cleaned off with, followed by handwashing and a paper towel.
Toilet paper is disgusting, as I see it. It moves things around, back there, but doesn't really clean you up. Gross! A portable sitz bath, with cold water and a teaspoon of baking soda, and a clean hand, followed by a rinse with plain cold water, and a hand washing session, will stop any and all troubles one may have with irritation, staining, and nauseating odors.
A bidet can also be used like the sitz bath, with a little creativity and minor modifications, depending on the model.
