well, the pits smell comes from bacteria eating your dead skin cells and sweat

the bootyhole smell comes from those things plus other things...

those "other things" being easier to clean if your butt is not a forest. also, each wipe takes care of a lot of the dead skin cells you'd find in your pitflaps

the real benefit of having hair in your crack is friction reduction

my cheeks get shaved, anything that's between the midpoint of the gravity well and the event horizon gets trimmed

gotta keep that little slidey slide happenin betwixt the rubbing bits of the cheeks, you dont know what you have there until you go through the stages of raw holecheek grief and them lil hairs are fantastic little anti-chafe lifesavers

can't imagine the waxed life, not for me
