Robbie is one of them. He's a certified bottom who can’t believe his luck when he sees the fifty men at his disposal...
But who would they be? These are top of the range gay sex workers, so porn stars are likely candidates for the job. For Robbie they need to be excellent tops, so I think Tom Wolfe would be high on his wish list. He's very good at that particular job - just as long as he remembers not to smile and keeps his fuck face on
Who would be on your list, though?
