Before the pandemic hit and my gym closed I’d say that easily 60% or more of the men swimming laps wore Speedo/brief/bikini style suits. I would wear a thong to do laps if it were allowed, sadly it’s not. So, I would wear the next best thing, a rio style back. Occasionally I’d get a raised eyebrow, but nothing more.
BTW Sam that blue wet look thong looks wonderful. I’m sure there were more than a few admirers watching when you were at the resort.
