Then I would have every reason to assume their methodology is completely screwed up if they managed to get those figures.
I have posted this website before (NSFW)
www.adultwork.com. Please can you tell me if what you are saying is true we see absolutely no evidence of it whatsoever? This website has been around for years, we have ample evidence of what I am saying is true. It is also true that to make it as a gay escort you need to be a lot more attractive than any women would have to.
I would also say there is also a difference between someone who has taken money for sexual favours (eg. Lets imagine a gay club some guy you're chatting to offers you $20 to blow himn in the bathroom.) To a woman who sees 20 men a week and has her own escort profile on a adult website as her job. They really are not the same thing and cannot justifiably be lumped into the same figures. I can imagine things like this are probably part or most of the reason the results might come out this way. I would also question the wording of the last point, as "compensation" sounds sufficiently vague that could mean money but could also mean other things. Maybe the boy had sex with some guy who also said they could stay at his house. Technically if that's how the study was worded that would then be counted.
(The people paying the boys would still be men, btw.)
