Interesting note. I've been to Thailand about 20 times, working mainly, and I've spoken to a few of the girls I've worked with (in a large bank). However I've never taken it any further as I know that all I have to do is go down to NEP and pick up a great girl for the night for a few bucks.
If you search thru this forum and the old one you'll see a hundred entries telling you that you're not going to get a 'real' girl because you're a farang. Perhaps all those well-meaning people were wrong. That advice has certainly put me off trying anything on with these girls.
Next time I go I'll put a bit of effort into talking to some of the girls I work with but if I do then I'm not going to get a shag that night (on the assumption that nice girls don't fuck on the first date). Having said that, I can always drop the 'nice' girl home after dinner then go down to NEP and get up to my usual tricks
Do us a favour and question your girlfriend a little further on this subject. I'd be very interested in what she has to say as one of the options I have at the moment is a transfer to Thailand and I'd love to meet a normal girl and try a relationship with her.
Thanks.
