I just finished watching this documentary episode of the National Geographic of their series 'Taboo' on Prostitution around the world.
They start off in in a red light district of a town in Bangladesh, go on to the high-end brothels of Sydney Australia, over to the streets of Washington D.C., then on to discussing sexual services for the disabled, and finally to a brothel in Prague where the clients and the ladies 'encounter' is live-streamed on the internet!
Overall it's an interesting presentation and discussion of the prostitution industry around the world and of the different people engaged in it and the varying attitudes towards it. A good watch for those who have 45 minutes to spare.
