Well I may or may not have taken a bit of artistic liberty there ya know for effect, to get a point across, or not.@HipHugHer - curious, how often do you wash your clothing and/or change them? And no chaffing if you just leave the fromunda there for weeks? I'm assuming you don't get head.
I'll go 3-4 days in the winter, tops. Beyond individual chemistry, most people find their need for bathing changes greatly as they age. I used to use dish soap my hair would get so greasy. Now, I wash my face with body wash and just run a little of that soap quickly across the scalp. Otherwise dry and itchy for 2 days.
I'm not a clean freak but I do bathe ya know. Depends on what you're doing but I guess call it 3 or 4 days out of 7 or every other day as an average. If you're working on cars getting covered in grease or you're doing manual labor out in the sun and heat that's one thing. If you're sitting in the air conditioning all day that's a whole different thing.
In the former you actually get dirty and sweat a lot and need to clean yourself. In the latter (office worker) the only funk that gets on you is that which comes from inside yourself. That means your ass, and a little ball, armpit, and foot funk after a couple days.
The social expectation of smelling like soap instead of human all the time is bizarre. At the same time there's an obvious difference between a little recent funk and the stuff that's been taking up residence for quite a while.
