2000 guys pay $5 to be in a sex lottery for a porn actress. But the actress can turn down the guy who wins. He gets his $5 back, out of the actress's share of the money. Then they pick another guy at random, until one is acceptable to her.
Guess it would have to be made in Nevada or outside US to be legal.

I like the idea.
But don't like the next part about her turning it down. To make it more interesting, there needs to be more of a penalty than $5
