More men should wear these at the beach. I like them and like seeing men who do wear them..
As I said previously, for me not wearing a Speedo/thong is an issue of comfort--I don't care what it looks like. I am with you on the prudery, can't imagine what's going on in the minds of the young men I've seen who wear underwear into and even during a shower at the gym: etymologically, gymnasium implies nakedness (Gk,, gymnos). Who 'fucked up' these young men?
Thongs look very gay. That's not an insult, but it would be like wearing an advertisement to the wrong audience.
I wore speedos when I used to swim competitively. If I was visiting a country where they were the norm, I'd be fine to wear one. Here in the US, it would feel a fashion faux paus to wear one to a public beach... not offensive, per se, but like wearing socks with sandals.
