2. Amsterdam, Netherlands
Is there a place with a greater sense of sexual liberation than Amsterdam? De Wallen, Amsterdam's largest red light district, is home to an insane amount of sex shops, sex museums, sex theatres, and special places where you can get some bud—like coffee shops. In Amsterdam, you'll gallivant through the streets of De Wallen, Singelgebied, and Ruysdaelkade, and take a peek at the sex workers advertising their services legally. Now, just because you can look, doesn't mean you have to touch, but you have choices, and that's pretty hot. The freedom to express yourself sexually earns Amsterdam its spot on this list.
