Not in Hua Hin. Many Western guys are with ugly hookers, many Western guys are with beautiful Western women.
Westerner, including me think all Thai women are exotic at first. Roll on a decade or 2, we realize they are not.
Also, the Westerners with Thais mostly can't fit into Thai society as their women is on the lower rung of the hierarchical social ladder and the man doesn't even get on the ladder.
