There aren't many non-Thai ladies here. Nearly all the foreign ladies you will meet here are wives of an expat, and the selection among the rest is slim pickins. Sometimes it had made me want to jump on an airplane to the next likely oasis, e.g., Australia or India. (I believe there's just too much materialistic expectation and homogenization most everywhere else.)
If you like partying and excitement, then the bars in Bangkok are some of the best in the world. For me, they were at first interesting to experience, and the music at some is always good.
It doesn't take long to get to understand the scene. It doesn't have much appeal to me as a rather studious expat, and the music and friends are the main draw.
I should make clear that I don't want to imply that all Thai prostitutes are trouble or all "ordinary" Thai girls are true-hearted.
There are gold diggers everywhere. You have to ask why a girl is attracted to a relationship with you, a foreigner, especially if she is quick to it. It is my experience that most ordinary Thai girls are not after my money (and don't take any), but I am picky and patient. Your mileage may vary. A sizeable percentage of non-prostitutes are attracted largely to the farang's money and material wellbeing, and/or some Hollywood-based illusion they may have of life in a farang's country. They may simply look to a farang to take care of them, everything, whereby they'd "have it made in life". Matrimonial prostitution (though they don't see it that way).
Notably, I usually don't make introductions and wouldn't be seen with many of the farangs who have expressed wanting a good Thai girlfriend (often in a fleeting moment of frustration over the behavior of a prostitute girlfriend they've become emotionally attached to), because I don't think those farangs really understand what they're getting into when it comes to good Thai ladies, would be unlikely to develop or enjoy such a relationship due to inability or unwillingness to adapt culturally (as well as the Thai lady's inability or unwillingness in many cases, too), and/or would be unfaithful to the good Thai girl which in many cases is damaging to her reputation and sometimes her life (e.g., offspring abandoned by the farang). In any introduction, I take no responsibility for anything. Use at your own risk.
