Hard to generalise about Ang Mo's liking Asia.
Many come here just for work and better pay. Nothing special
about Asia in their minds.
Then there are those male Ang Mo's who are old, poor by Western
standards, single or divorced, and then go to Thailand or
Philppines and find an Asian wife cuz people there are so desperate
to escape poverty that the white men feel like kings, instead of
the bums and losers they are back home.
The male Ang Mo's who are more educated and cultured will head
to HK, SG or Japan and they may also find the hot slim elegant
Asian babes treat them as something special. Sex is always
something that interests guys.
Dont know if there are any female Ang Mo's who stay in Asia
purely on their own decision. Would expect most stay cuz husband
have job in Asia.
