Maybe its because I don't take these horrific poo's or have excessive ass hair or ass sweat but I've never cared to have my crack 100% clean...seriously, clean or not its still a butt hole/ass crack.
I drop a bomb, do a few wipes, call it a day. I don't really obsess it I got some shit crumbs or smears..the residue is locked away under 2 layers of clothing and nobody is going next to my turd cutter.
Average day tho its just shit all day with a few wipes to remove what I can and then pull up and go, I don't think twice about the 10% of poo matter in my crack...cause its still an asshole no matter the cleanliness. Hop in the shower after work and remove the sweat and poo of the day then dress and restart funking myself up till the morning shower.
If I suspect I'm getting laid later that night I'll poo before getting in the shower to go out, if I poo at some point during the day and surprise sex happens I just avoid recieving oral just to be safe.
There's billions of Americans who do the same as me everyday..shit, wipe, be 80-90% poo free and not give a heck, and in doing this has a stigma of shitty ass Americans become a relevant thing? No.
Instead quite a few of these ass washing countries are cesspools of disease and sanitation. I'd rather be intimate with a shitty ass American then risk getting a paper cut in some of these countries with sparkling clean assholes.
In the end, it will always be a butthole/ass crack and even if there's no residue in or around the outside just millimeters into the balloon knot is poo. So unless there's a wash and an enema then its still filthy.
