Giraffes on the Serengetti don't giggle when an unclothed giraffe of the opposite sex walks by. I spent a lot of time for work in the south of France. All the beaches are topless. I thought it was cool for about 5 minutes and then it was mundane. For some reason we have manufactured shame for the display of the human body. It's not dirty and it's not nasty. The hundreds of nude paintings in the Louvre were not created by pornographers.
