I'm American and I wouldn't recommend Prossies here. Way too much trouble. Chicks are just in it for the money, Law Enforcement, overpriced and a whole other laundry list as to why it doesn't make sense. If you're in somewhat decent shape, Swinging and swinger clubs are the way to go. You'll have to work your charm a bit, but you do go in knowing that everyone you meet at one of these establishments is looking to have sex. While it may or may not be with you, half the battle is already won. DC is hard, but PM me for NYC info.
