I've been in Manila for the past week and noticed quite a few crossdressers and transsexuals. The reason must be that it's easier for Asian's, who are genetically petite, to pass. I've also read that the Philippines, and especially Manila, are much more tolerant of "baklas" (gay/transgendered, whatever) than any place in the US. I thought that was interesting.
My manager had a pedicure done by a transsexual who said that most travel to Switzerland to have sex reassignment surgery done. No idea why; I would have guessed Bangkok or Hong Kong.
Crossdressing pops-up everywhere!
