In literary representation, the distinction between the genuinely erotic and the licentious is a distinction not of subject-matter, but of perspective. The genuinely erotic work is one which invites the reader to re-create in imagination the first-person point of view of someone party to an erotic encounter. The pornographic work retains as a rule the third-person perspective of the voyeuristic observer.
