[Suzerain of Sheol]

One of my favorite series, The Prince of Nothing trilogy is full of over-the-top graphic sex, but the way it's written actually works for me. On one hand, it adds an element of icky horror to his orc-equivalents that makes them a lot more terrifying than the generic bad guys in most fantasy. On the other hand, the normal sex in the books feels completely unromantic, and often disgusting, which is the point, since the world of Earwa... just sucks. Despite how often it comes up in the story (one of the main characters is a prostitute) it never really feels gratuitous.
