I’m glad that I’m not alone:)
I saw a few of you mentioned shopping in person... actually in Western Europe and Japan, the department stores always carry men’s thongs. You can find not just the skimpy ones, but also sheer ones. I missed the days when I often traveled for work.
I always find it interesting that many department stores in Asian countries carry men's thongs (they're even hard to find at Aussie dept stores). I've been to a few countries in South East Asia (Singapore, thailand, malaysia, indonesia, etc.) and most major stores carries a thong of some kind.
with japan, thongs for men are a bit more normal i'd say since japanese men wore thong-like loincloths as underwear up to ww2 (and still do for many traditional ceremonies)
