I have a private pool, and I wear a pair of speedos to swim 600 yards every day. That is what speedos were designed for, swimming. My wife would NEVER let me wear them in public, so I wear boxer style swimming trunks aboard ship.
However, I do feel that speedos on men fall in the same category as teeny weeny bikinis on women. I confess that I would much rather see a lady in a bikini than a man in a speedo, and I don't want to see either in a thong. Isn't life unfair when men can go topless and women can't?
