Perhaps you are completely ignorant or the western countries teeming with 'blended families' and divorcees remarrying (twice, thrice etc.) or perhaps you have a superiority delusion that you are 'better' than 'them'. In any case good luck following the Thai males you want to replicate.
Not very fair as Thailand welcomes with open arms all the Korean whore-mongering, whiskey swilling, cigarette smoking old men coming to 'holiday' in Thailand.
