sexual desire and attraction was a starting point- the guy that talked me into going over there was a rampant sex tourist. He had married a Thai prostitute- in the days when he married, no Thai woman with any face at all would be seen talking to a white guy or a US soldier.
I spent about three weeks touring the country on my second trip and learned a lot about the culture, the history of the country, Buddhism, and the outlook of thai people in general. The weather and the food were also a major turn on.
I decided that I wanted to live there soon after this second trip.
So- learned a little culture, learned a little language. Sought a Thai wife despite the handicaps of having a divorce and a child from a prior relationship and being a farang.
After the first Thai marriage fell apart, I was dating Russians and Ukrainians in St. Petersburg, Moscow and Kiev. Even brought over a likely prospect.
Now I have the Thai wife, have the car, have the house. . . and nine years or less to run before I plan to be there at least 75% of the time.
