I usually get light to moderate brown skid marks in my Fruit of the Loom white briefs when there dirty. No matter how good I wipe with toilet paper after I'm done going poop in the potty, I will always get them along with light piss stains. Most young guys out there like me have this problem when are underwear dirty and there's nothing wrong with that. That's why I always shower and put clean underwear on every night before I go to bed and sometimes at the gym after a shower, only if I happen to shower after working out. Skid marks has always been a part of life for me since I was a little kid and I've been very use to it. Dirty smelly underwear with skid marks is what turns on a guy or gal.
Just a thought : if one has to change one's underwear every day, then one can't be keeping oneself very clean, can one?
.........excepting those whose work naturally makes frequent changes of clothes necessary, of course!
I sell my dirty underwear (usually wear boxerbriefs). Custom requests accepted.
into swapping worn underwear. I like them very worn. Hit me up if interested. Iam into skids.
