If you are not into asian in general, that's fine, but it seems like you don't like asians just because those you saw in Thailand are femine. (you really sound like my mother, just because she had some gay patients acting femine in the hospital going crazy when she was working as a nurse years ago, she thinks all gays act the same way ! And she is really homophobic as well) Do you realize many asians are actually masculine and at least averge build if not stocky ? I am one of those, and in general, majority of north asians are masculine, like Chinese, Japanese, and Korean. As the culture of China, Japan, and Korea are very hard to accept man acting femine unlike south asia like Thailand and Phillipines.
I suggest you go to different countries in Asia to explore yourself before being jugemental !
