I just returned from a two week trip to Thailand. In Thailand crossdressers and the transgender community in general are referred to as Ladyboys.
You will be happy to know that they are not looked down upon in the slightest by their culture. Prostitution does not carry the stigma that it does here either. The disturbing part though, is that many of them are raised from childhood to be ladyboys inorder to engage in prostitution.
My friends and contacts there were involved in working to help prostitutes get off the streets, but that is a whole other story.
On a brighter note, I did go to a Ladyboy Cabarret and the girls there were simply gorgeous. They were so pretty and very entertaining with their dances and costume changes.
