Interesting points in the last 2 posts. I'm not quite so sure about the Vietnam War, though, as it ended in 1973. I expect some of the GIs may have been after boys, but whilst girlie go-go bars had certainly started to sprout up, there were few if any gay go-go bars by then. Even in 1980 Bangkok had less than a handful. But the western clientele during the 1980s and 90s was certainly a lot younger on average than in more recent years.
