On HBO, there is a series called "Cathouse", which documents the girls at the Bunnyranch in Nevada.
Just recently, on episode 11 I think, almost ALL of the girls except for one, didn't care what size their clients where.
Most agreed that big guys hurt (and they're prostitutes!), and realized that big men think that their cock is big enough to automatically please a girl, when in reality the average guys and small guys are much better in bed, because they realize that a big dick doesn't do shit if you can't use it.
Something to think about... (prostitutes agree, there is such thing as too big, or at least know how to wave your wand).
