Why go to Nevada, when bi men are so plentiful all over the place?
Convenience. In a brothel you have to pay for it, but you also save the time finding it and seducing it. Time is money. ...
It's not an it, it's a he!! Besides, finding and seducing is most of the fun!
Because you get to pick.
You can do that in a pick-up bar. In a brothel you actually get what you pick.
