I found this post extremely disturbing. Reading some articles in the NYTimes and other sources leads me to believe that many sex workers and "entertainers" around the world are in conditions little different than slavery. This is true even in the US and Europe. As far as these "boys" seeming happy, remember many of the accounts of the pre-Civil War South comment on the contentment of slaves. This sounds far to much like exploitation of poorer and possibly underage people.
Sorry for the "soap box" rant.
