ABSTRACT
In this chapter, we discuss numerous philosophical accounts of sexual perversion. Although I argue that all fail to capture what sexual perversion is, we derive some important insights about sex and sexuality from discussing them. I then offer what I consider to be a recipe for a plausible account of sexual perversion, though I shy away from giving a full-fledged account. Next, I turn to sexual fantasy, discuss some of it kinds, and discuss the following questions: (1) whether there is something ethically wrong about sexually fantasizing about someone else while having sex with the person you love or are in a relationship with; and (2) whether having sexual fantasies with morally troubling content reflects badly on the moral character of the person who has them. I end the chapter with a discussion of the fantasies and desires involved in BDSM.
