Paraphilia

Paraphilia (from Greek para παρά = beside and -philia φιλία = friendship, meaning love) describes sexual arousal to objects, situations, or individuals that are not part of normative stimulation. Paraphilia involves sexual arousal and gratification, involving a sexual behavior that is atypical or extreme. The term was coined by Wilhelm Stekel in the 1920s. Sexologist John Money later popularized the term as a nonpejorative designation for unusual sexual interests. He described paraphilia as "a sexuoerotic embellishment of, or alternative to the official, ideological norm."
