Query: The unsexiest book about sex I've ever read

The phone sex premise is intriguing, but I was sorely disappointed. Despite the kinky sex fantasies, I was amazed Nicholson Baker could turn them into something so unsexy. I found it downright tedious, over-intellectualized, and pretentious. As I read, I kept thinking, "Who talks like this?" I gave it two stars instead of one because, to be fair, Vox is well-written. Too bad the pretty prose is wasted on a snooze-worthy non-story.
