New developments in understanding the nature, etiology and treatment of compulsive sexual behavior offer new hope for people suffering from these sexual disorders. There is considerable debate about terminology and these newer approaches to treatment. This paper reviews these new developments and the controversy which surround them. Compulsive sexual behavior can be divided into two types: paraphilic and nonparaphilic. While John Money (1986) has described the paraphilias at length, a specific attempt is made here to describe and classify nonparaphilic compulsive sexual behaviors. An obsessive-compulsive model for understanding paraphilic and nonparaphilic compulsive sexual behaviors is preferred by author.
