You may be hansum men, but you seem well confused. Are you too proud to post in the Newbies section?
If you want to hook up with regular Thai girls you had better be able to speak the language, learn something about Thai ways, and be prepared to put in plenty of time courting (which will cost you plenty); they are not known for putting out on the first date or early in a relationship. If it is a bit of stray you want, then be prepared to pay.
