Lots of men prefer wearing women's used panties instead of new, unused panties.
Not really into the having them been worn by a woman before me. Since I don't wear ones with a cotton lining and either find vintage ones in thrift stores or on ebay with a double nylon crotch, the newer the better as far as I'm concerned. I've got some from 40 years ago still in their original package that I will break out and wear on special occasions.
I will wear my wife panties and will purchase used ones if the crotch isn't raunchy looking, but must be to my likings before I purchase them
There was a time when I did, but no longer. I wear fresh panties each and every day, some which my wife bought me. So why wear used panties? Besides I wouldn't want to get a UTI nor a STD.
