paraphilia
n. in DSM–IV–TR, any of a group of disorders in which unusual or bizarre fantasies or behavior are necessary for sexual excitement. The fantasies or acts persist over a period of at least 6 months and may take several forms: preference for a nonhuman object, such as animals or clothes of the opposite sex; repetitive sexual activity involving real or simulated suffering or humiliation, as in whipping or bondage; or repetitive sexual activity with nonconsenting partners. Paraphilias include such specific types as fetishism, frotteurism, pedophilia, exhibitionism, voyeurism, sexual masochism, sexual sadism, and necrophilia. In DSM–5, a paraphilia is considered a paraphilic disorder only if it causes distress or impairment to the individual or if its practice has harmed or risked harming others. —paraphiliac
