The psychiatric literature suggests that paraphiliacs can be expected to participate in only one type of deviant sexual behavior. Using self-reports gathered with assured confidentiality from 561 nonincarcerated paraphiliacs, we discovered that most paraphiliacs have had significant experience with as many as ten different types of deviant sexual behavior without regard, in many cases, to gender, age, and familial relationship of the victim. The relevance of these findings to our understanding of paraphiliacs and their treatment is discussed.
