Sexual fetishism or
erotic fetishism is a sexual focus on a nonliving object or nongenital body part. The object of interest is called the
fetish; the person who has
a fetish for that object is a
fetishist. A sexual fetish may be regarded as a non-pathological aid to sexual excitement, or as a
mental disorder if it causes significant psychosocial distress for the person or has detrimental effects on important areas of their life.
Sexual arousal from a particular body part can be further classified as
partialism.
