1. Rio de Janeiro
What’s the first thing that comes to your mind when someone mentions Rio? The hottest carnival parades and balls, right? This city ranks high when it comes to the sexual activity and experimentation and saying that it’s the most sexually active city in the world is not a mistake. Moreover, Rio is another Brazilian city on our list of the most sexually liberal cities in the world in 2018; therefore it’s more than obvious that Brazilians enjoy their sex lives.
