Since we were talking about Thai ladyboys, just commenting on a phenomenon that seems to be trending in more countries, not only in Thailand: "With Manicures and Makeup, Japan’s ‘Genderless’ Blur Line Between Pink and Blue" (just discovering the New York Times: Interesting stuff):

Along with his manicured nails, bobbed hair and high-heeled shoes, the makeup made Mr. Sasaki, 23, appear more typically feminine than male, a striking choice in a society where men and women tend to hew strictly to conventional gender dress codes.

Mr. Sasaki, a model and pop band member who goes simply by Toman, does not regard his look as feminine so much as genderless. As one of a small but growing group of “genderless danshi” — “danshi” means young men in Japanese — he is developing a public identity and a career out of a new androgynous style.

“At heart, I am a man,” said the petite-framed Mr. Sasaki, whose wardrobe of slim-fit tank tops, baggy jackets and skinny jeans evokes the fashion of a preadolescent girl. The concept of gender, he said, “isn’t really necessary.”

Just as some American males have embraced makeup, young Japanese men are bending fashion gender norms, dyeing their hair, inserting colored contacts and wearing brightly colored lipstick.
