Some men just love Asian women, but yes a Thai women is kinda scraping the bottom of the barrel.
Give me a flat ass Korean or Jap girl any time
There's different races in Thailand. What you see in go-go bars is Isaan girls - who are darker skin, uneducated, super street smart and usually married to a Thai guy. Then you have Southern girls who are much darker skin but it wears well on them. On the other hand, the lighter skin Bangkok girls are either native Thai or Thai Chinese. These are better looking girls and not after your money.
This chick is 42 years old in this pic. 100% Thai and typical of what you'd find in an office girl working somewhere like Wireless Place. No penis that I am aware of.
Of course, none of them see sunlight - they wear that white skin with pride. Having lived in Japan - I gotta admit there is a stunner everywhere you look. Not the same in Thailand.
