Black males in popular film

I recently watched "40 Year Old Virgin," and observed the representation by one of Steve Carell's friends in the movie. Jay, played by Romany Malco, plays a suave, philandering ladies man, encouraging his friend to have sex for the first time. I noticed that almost all of the comedy surrounding him had to do with his overt sexuality, and the fact that he constantly cheats on his girlfriend. Although all of the men in the film talk about sex, since it is the center concern of the movie, I found that he was the only one who discussed cheating, with no sense of guilt. This gives him a pretty empty shell, making his sexual deviance his main characteristic.
