There was this Tyra episode that I watched on youtube called "Gay for Pay" its about these guys who claim to be 100 percent straight, but do "gay things" like flirt with guys in gay bars, or do webcam shows to get paid. They say that they aren't gay, nor to do they get turned on by guys, but they accept the pay. I think that's a little shallow, and I'm sure a lot of people on this site will agree with that statement.
I would be careful though. You don't want to just meet up with some random dude, expecting to get 500 dollars for your dick. Even if you can handle/take care of yourself, you should be weary and cautious about something like that.
If you want to get paid for your cock, you'd be better off doing solo porn haha.
Also, I don't think you should be worried about if you think you're 1% gay. Sexuality is a label that you don't need to live by. Just live your life how you want to.
