Of course if you are near family upbringing, you won't be able to get away with it.
I don't think anyone brings their bar girl back to their home country and tells everyone what she did for a living.
People are away from their families back home in Thailand, which gives more freedom.
"Polite society" tries to keep everyone in line to conform, and also polite society is hypocritical. Because many Chinese and Indians will sleep with these girls while their wives are back home, but hide it from them.
So is it worse to marry one or come here by the busload and lead a double life with one while being married to a normal girl?
Trick question.
