Here's a "trick" I discovered at Burning Man:

Instead of wiping with TP after peeing, bring your water bottle and sacrifice some drinking water to instead rinse off any pee residue. The extra bonus is that there is no need to dry off because of the incredibly low humidity on the alkali dry lake bed.

There are two benefits:

Rinsing gets one cleaner than wiping - there are no salty residues left behind to irritate.

Not using TP at all means less frictional rubbing. With hourly peeing, the friction can rub you raw in the harsh desert environment!

Even away from the desert, when wearing cycling shorts, "not wiping dry" is an option. The shorts are probably damp (with sweat) anyway - a few extra drops of clean water won't make a difference.
