The term paraphilia denotes any intense and persistent sexual interest other than sexual interest in genital stimulation or preparatory fondling with phenotypically normal, phys ically mature, consenting human partners. In some circumstances, the criteria "intense and persistent" may be difficult to apply, such as in the assessment of persons who are very old or medically ill and who may not have "intense" sexual interests of any kind. In such circumstances, the term paraphilia may be defined as any sexual interest greater than or equal to normophilic sexual interests. There are also specific paraphilias that are gen erally better described as preferential sexual interests than as intense sexual interests.
Some paraphilias primarily concern the individual's erotic activities, and others pri marily concern the individual's erotic targets. Examples of the former would include in tense and persistent interests in spanking, whipping, cutting, binding, or strangulating another person, or an interest in these activities that equals or exceeds the individual's in terest in copulation or equivalent interaction with another person. Examples of the latter would include intense or preferential sexual interest in children, corpses, or amputees (as a class), as well as intense or preferential interest in nonhuman animals, such as horses or dogs, or in inanimate objects, such as shoes or articles made of rubber.
A paraphilic disorder is a paraphilia that is currently causing distress or impairment to the individual or a paraphilia whose satisfaction has entailed personal harm, or risk of harm, to others. A paraphilia is a necessary but not a sufficient condition for having a paraphilic dis order, and a paraphilia by itself does not necessarily justify or require clinical intervention.
