Sexual fetishism, or erotic fetishism, is the sexual attraction to materials an objects not conventionally viewed as being sexual in nature; the term was first introduced by Alfred Binet, the psychologist better known for inventing IQ testing. Fetishism is diagnosable as a paraphilia in the DSM and the ICD, but many people embrace their fetishes rather than seek treatment to attempt to be rid of them. Body parts may also be the subject of sexual fetishes (also known as partialism) in which the body part preferred by the fetishist takes a sexual precedence over the owner. Sexual fetishism may be regarded as a disorder of sexual preference, or as an enhancing element to a relationship. .
