Couples Enjoying the Swinger Lifestyle Attend a New Resort to Live Out Their Fantasies

From the outside, the resort looks just like any other along the sun-soaked beaches of Los Cabos, Mexico: pools and bars and volleyball. But before long, it's easy to see signs that this place is different. In the gift shop, not far from the sun block, were boxes of Viagra.

It was very quickly clear that at this clothing-optional resort, most enjoyed that option. Nudity was the norm. After all, this was Desire, the second-best-known "swingers" resort on the planet.

Banking on a Demand for Something Different

On the hit ABC show "Desperate Housewives," cheating destroys marriages because spouses lie and get caught.
