My bum + taint are chaffed raw I believe the cause is the hair down there.. shaving it sounds difficult to do, and would require a lot of time and maintenance to keep shave. So it was stabbing in 2-3 days.

Not overweight. 5'-8" 160lbs

Thoughts, remedies?

try Nair.

The only time I've experienced chaffing is when I did shave. Idk tho, give it a shot

It's hit or miss also... I'd say I have the issue 1 out of 4 runs.

clothing is the same, under armor boxers and Gym shorts

DO NOT SHAVE YOUR ASSHOLE HAIRS, IT'S THE WORST THING FUCKING EVER. THERE'S A REASON NATURE PUT THOSE HAIRS THERE OMFGOFGMMGFOGFM DO NOT DO NOT DO NOT DO NOT!!!!

I have chafing in those areas too it sucks sweat all day at work (machine shop) and walking / standing all day
I usually put bag palm on it after shower then when I wake up next day and it goes away for a week or so

Baby powder helps and depends on boxers sometimes too

Use veet/nair

I do it regularly. Never have any problems

I use an electric trimmer , basically a nose hair trimmer. Works good.

I am overweight and incredibly hairy and I don't have this issue.
