I don't. It's pure wild-eyed speculation ... and an off-color joke. But don't be shocked if there's some truth to it.
I had heard they had panty dispensers, but didnt realize they were used.
"Used" is the whole point. It's catering to a weird fetish. It seemed to me that the alleged "user" was often supposed to be a very young woman, perhaps under-aged girl.
I read someplace that there are many sex fads in Japan, and that they are constantly changing, so as we speak, these are probably passé and something else has taken their place.
I know that women in America have marketed used panties, though. I used to clean for a mental patient who was corresponding with some. He left the letters out with lists of different things they would mail him for a fee. He also left their pictures out. I don’t know if he sent them any money. I doubt it because his money, disability and stuff, was controlled by a payee. The payee hired me but I quit because I got tired of him leaving this stuff out all the time. Most clients would put it away before the cleaning lady came over.
If you are discharged from the Army because of mental illness, you don’t get a pension, right? Just wondering.
