People with fetishes have sexual urges related to non-living objects. The person becomes sexually aroused by wearing or touching the object. For example, the object of a fetish could be an article of clothing, such as underwear, women's shoes, or lingerie. The fetish may replace sexual activity with a partner or may be worked into sexual activity with a willing partner. A related disorder, called partialism, involves becoming sexually aroused by a body part, such as feet, breasts, or buttocks.
