I haven't worn boxers in a long time I should go wear 'em before they get...
what's a bad thing that can happen to underwear if you don't wear 'em for a long time? I wanna say "feel neglected" but that assumes a terrible reality where underwear are sentient

before they get smelly? crusty?

moldy?

ah, yes.moldy.
what, are mushrooms gonna grow out of them? XD

well if I wear 'em something's certainly going to end up growing :v

good point there.

the troubles of being a grower not a shower

another option is before they get eaten by moths

okay this particular pair of boxers has weakened to the point that I pull it up ever so often

it's an Iron Man merchandise boxers that I got from a cousin as a gift... 2015-ish?

it's got his iron man face on my butt

IMHO,it's better to have it on your butt than on the other side.

try separated underwear? also wash your boxers before wearing them if it has been too long

i just suddenly remembered something because of Oshinko 's comment "crusty"
some girls in japan will sell their used underwear (it's put in a vendo iirc? no direct contact between girl and buyer).
needless to say, it's a kink. the more stains etc it has, the higher the price.

wanderer : what is that, a sort of pantsu gacha? XD

sorta, but vendo xD the luck gods have no place in this kink

Pantsu gacha exists?!

Not used though, I think.

Faramond : offtopic: ah, are those toy pantsu? or keyholder pantsu? also, waaaaaaaannnnt! XD

Oshinko : I am not too sure. I just saw it while looking for an article for "used panties vending machine".

However, if that's the same gacha egg as most others, I doubt it'd fit an actual panty in there.
