A paraphilia is an experience of recurring or intense sexual arousal to atypical objects, places, situations, fantasies, behaviors, or individuals.[3][4] It has also been defined as a sexual interest in anything other than a legally consenting human partner.[5][6] Paraphilias are contrasted with normophilic ("normal") sexual interests,[7][8] although the definition of what makes a sexual interest normal or atypical remains controversial.
The exact number and taxonomy of paraphilia is under debate; Anil Aggrawal has listed as many as 549 types of paraphilias.[9][10] Several sub-classifications of paraphilia have been proposed; some argue that a fully dimensional, spectrum, or complaint-oriented approach would better reflect the evident diversity of human sexuality.[11][12] Although paraphilias were believed in the 20th century to be rare among the general population, recent research has indicated that paraphilic interests are relatively common.[8][13]
