David Lodge claims, in Author, Author, that Queer Theorists purport to have identified an extended metaphor for anal fisting in Henry James' introduction to the revised New York edition of his works. I would be fascinated to read a description of anal fisting in the rather orotund style of the late Mr. James. I lack the dexterity to write sentences of over one hundred words so the challenge is all yours...
