22. Bangkok, Thailand
Bangkok. For those whose minds are always in the gutter, the name speaks for itself. The Thai have no qualms about being sexually liberal. Go-go clubs are everywhere and if you have aches and pains in certain special spots, someone at one of the many massage parlours may be able to get thoses kinks out for you. The Khao Sanh Road club district is really where the partying happens. Infamous for being a hook-up spot, the odds of your night's activities culminating with a happy ending are in your favor.
