The 10 most promiscuous cities in the United States (+Photos)

4. Miami, FL

Miami is a good choice for number 4, as the city has a large population (about a half-million city residents and over 5 million in the metro area), filled with sexy Cubans, steamy hot, sweaty weather and a plethora of hotels in all price ranges – at last count there were 374.

Skimpy bikinis are out in full force, waiting for the muscle-bound jocks to make their move. It’s a perfect recipe for oodles of casual sex encounters.
