Recently I've heard from a few people a desire or interest in trading underwear. Not necessarily 'soiled' or stained, just a fun little trade for the kink and enjoyment of it - the sort of fun of knowing you're wearing someone else's boxer-briefs or your jock strap is being worn by some stud in Idaho. Does anyone know where to make this happen? Sites that initiate such trade or places where men interested in such deals can work something out? Thanks!
