Yes and I posted about it a year ago, but it has nothing to do with my ass being dirty. I use wet wipes and water after shitting and my ass is always clean other than the sweat.
My ass sweats even during winter. I leave wet streaks on any chair I sit, especially plastic. All chairs/seats at my college are black and plastic so sweat is really visible on them. Whenever class ends I have to squirm in my chair to "wipe" the sweat and sort of lift my ass up off the chair for a few minutes before everyone gets up so that no one sees the sweat on the seat. I avoid sitting in public transport.
My ass also sweats when I have to take a dump. Sometimes my underwear is completely soaked if I hold my shit in for longer than a few minutes.
During summer it's not only my ass that sweats, it's also the back of my thighs and knees and it all drips towards my feet so that my entire pants get wet. I can't wear regular pants during summer unless I want everyone staring at my wet legs and ass. During summer my ass and legs sweat even just standing. Not even shorts help if I'm sitting.
It's just another part of being a subhuman with terrible genetics.
