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

2. Seattle, WA

Seattle is known for having a rich musical background, with jazz as its noteworthy genre. It’s a gateway to Alaska and Canada, and the eighth largest port in the U.S. So aside from Seattle’s metropolitan area that 3.6 million residents call home, there is a great deal of coming and going through the city.

Generally, any city that has a higher than average quantity of transient travelers is going to be more likely to have more casual sex going on than cities that have a finite population. Add to that the large numbers of employees working at mega-companies, such as Amazon.com, T-Mobile, Microsoft and Boeing, and we think Seattle’s a prime selection for the number two spot on this list.
