You would be shocked how bad most people are at cleaning themselves. They think just being under running water is enough or only wash upper with soap and the "rest runs down and gets washed"
Been washing my balls n ass since junior high and guys would look at me like I'm insane when i mentioned i shampoo downstairs, is how i came to find out most of them don't even do basic soap let alone scrub down there
I use a towel twice. Once then hang to dry use again then done. I find if i try to hang to dry again it either doesn't quite dry by the next day or just has a kinda bleh texture i don't enjoy, not soft anymore. So 2 uses it is
