When somebody is in a desperate economic situation, people will do almost anything to get by. There is nothing remarkable of Swell80 convincing Central American so called straight guys to go gay for pay, there were several male prostitutes in Swell80's menu. For these people, money talks. I can believe that they are straight, and for them to fuck a gay or allowed a gay to suck their dicks, for good money, is nothing wrong. They don't see it as turning gay. They are just reliving themselves in a human body. How much is good money for them is something that I don't know, though.
