The male "talent" pool is not as large as the womens. I think from a directors point of view they can only shoot the meat puppet and "whore" together only so many different times and ways. And I agree with Guido the smilingarab with the female eventually being out-shot.

I personally could care less what color the dude is as long as the director shows the pussy getting worked over, the asshole being gaped or the throat being gagged. Then I'm a happy man
