My understanding of the younger generation is that the straight guys aren’t as afraid of gay stuff as they used to be. So the twist premise would probably just be a bunch of guys comfortable enough in their heterosexuality to suck a dick or two in order to win a game. Probably wouldn’t even need there to be a monetary prize at the end.
While it might not be as controversial to be gay as before, i would guess it still goes with a lot of stereotypes (even positive ones), and things even well meaning people assume or apply to gay people, some of them unknowingly.
Which is why I’m sure it would still be entertaining and interesting to see what a group of straight men think a gay man behaves like while assuming they are in a social group of actually gay men who try to identify the heterosexual.
