In my younger days I was a very good windsurfer, even had my own board (although I sucked at regular surfing when I tried it in Florida and Hawaii). If I escape to somewhere warm I'd like to get back into windsurfing. Can you think of anything more sexy than and old guy in speedos jumping the waves on a windsurfer?
Easily, but first and then, speedos should be banned regardless of the age of the wearer. There is nothing sexy or even remotely attractive about them.
