Don't know if it has already been said but here are my thoughts
1. Asians have a more slender frame to begin with which helps
2. The big thing is places like Thailand for instance many of the ladyboys start their transition very early like from 12 years old, they start taking hormones as early as that age and start becoming ladyboys early
3. Since it is more accepted or common in Asia it makes it easier for them to start.
Places like Canada, America etc if they started their transisition early it is a lot more difficult to get the drugs, be accepted and so forth, so many of the ladyboys , transsexuals start later in life
And to also throw one more point i have been to thailand , yes there is many beautiful ladyboys but their is also a lot of not so beautiful ones as well, just most of the adult sites are obviously going to focus on more beauty ones... but there are lots to choose from in Thailand, walking down a street i could see 50 in 5 minutes
