If a loose tunic top and loose fitting pants are worn, I don’t find them necessarily immodest. IMO, the idea that all men are checking out women’s crotches is a bit exaggerated. Men or women whose pants are tight are immodest. Guys who wear loose pants and do the “man-spreading” thing on public transport or in public are just as disgusting as any woman who thinks skin tight leggings or tights are trousers. Both are totally classless, in bad taste, and lewd. # for bare bellies, muscle shirts, short shorts, bare backs, top or bottom cleavage, undergarments that show, or too high hemlines. Most women do not have lovely knees and old men with bony knees best confine them to the backyard.
Both genders, if you swim in public, wear a coverup when not in the water. Use discernment in the kind of places you swim. If a pool or beach is referred to as a “meat market,” there’s a reason. Stay away, especially if you have children or are male.
A young adult male relative of mine had the experience of going for a swim at a campground with a river beach. He saw a few couples, a few guys, and a family off to the side, so he figured it looked tame enough. He dove in only to have two of the guys swim over to the ropes and invite him to a threesome in their tent! Obviously, he declined. Upon looking into the campground online, he learned it is a favorite weekend spot for rainbow types from Philadelphia.
I felt a bit bad because I recommended the place having camped there about 15 years ago. I used that beach myself and didn’t notice anything untoward. It seemed then to be a campsite for families and retired couples in RVs.
My guess is that had I gone there last year swimming, nobody would have given me a second glance. Young gαy guys will have no interest in a mid-60’s lady in a swim dress who paddles around, cools off, then dons a coverup, and retreats to a chaise lounge to read a book.
Had the beach been populated with older men by themselves, I’d not use it. A normal widower or divorced man still has youthful desires. If he thought I might have money, all the better! Young men won’t have interest that way in a granny, and I’m well past the age of being tempted by men young enough to be grandsons! Still, I avoid most public beaches or go only at certain times when not crowded.
