Spandex might have gotten a bad rap over the years (thank you, Richard Simmons), but on those who abide by the old chestnut about it being a privilege, not a right, it can be sexy in the right circumstances. That said, we can't say that everyone on this site is doing his part to rehabilitate this much-maligned fabric (or is even wearing it, for that matter)—but if you simply appreciate the pervy thrill of checking out guys on the beach who don't know they're being photographed, we guess it really doesn't matter what kind of bathing suit they're wearing.
