What bit of straight porn I have seen seems to have categories: in the pretty, sexy category [cheerleaders, high school girls in uniforms, secretaries, nuns, etc] is a hierarchy that reads White women first, Asian women second and/or Latina women second. In the later category is Black women who are often labeled ‘Black bitches’….they are usually attired in some animal print. Which is often the case even in mainstream magazines i.e. Vogue or Harper’s Bazaar. Zebra or leopard printed outfits = Black woman style. Again I am no connoisseur or expert, just a few things I have observed.
