Quote from Sebbie
Then around 1990 I attended a convention and stayed at a Hotel in San Diego. There, you often were wearing too much clothing if you wore a brief suit. I wore thongs most of the time, and thats what many of the guys around the pool and esp the hot tub were wearing. I have thongs and a skimpy brief style suit of the same color. I would slip the brief over the thong and head off to the pool or tub. Then I would check out what the other guys around me were wearing, and slip off the brief to reveal the thong or not, depending on what was going on at the moment.
On the subject of attire for pools or hot tubs, in Japanese communal baths, men wear nothing. The Japanese have got the concept 100% right and unless it's a coed get together, the best thing for the pool or the bath is pure nudity.
