There is a Documentary on the sex market in Dubai called Desert Nights. Its quite interesting. anyone who can bypass etisalat can find it at www.youtube.com by searching Dubai Desert nights.
I watched it, it is sad to know all this happens in a Islamic country. The administration is aware and doesnot want to do anything. U can see in this documentary that all this happens under the supervision of police.
Of course because someone's making money from it. If they weren't they wouldn't allow it. But you know it's the oldest industry in the world and to be honest, if it's regulated and safe as in other countries then it actually goes to stopping randy blokes just harrassing random women on the street, which used to happen alot here.
It offends the social, political, and moral values of the UAE, as it contains some 'raunchier' videos.
Alternatively, you can pop down to Bur Dubai to get your fix of 'raunchy'.
