I like your comment about changing attitudes. Men are being emasculated. It's a gradual process that seems to have gathered in pace over the last thirty or forty years. No sooner were women free to wear the skimpiest of bikinis and the shortest of micro-mini skirts than they began to carp about guys' junk being discernible in speedos. Nowadays, even one's fellow man thinks it's creepy to wear them. We have been brainwashed into believing such a display is almost indecent at the beach or swimming pool.
Women have breasts and pubic mounds. Men have dicks and balls. But some insane agenda takes over when it comes to swimwear. One sex dresses to accentuate its differences; the other sex dresses to mask its differences. It's NOT gay or obscene to have sex organs. A lot of guys admit to being proud to display a nice bulge in jeans and yet they think it wrong to wear speedos. I guess bike shorts will be the next thing to come under fire. Not that I wear them - I'm not a cyclist - but I expect we will one day have cyclists wearing overalls in the Tour de France!
