Candaulism, also called candaulesism, is a paraphilic sexual practice or fantasy in which one person exposes their naked partner, or images of their naked partner, to other people for their voyeuristic pleasure or the pleasure of their partner.^[1] Candaulism is associated with voyeurism and exhibitionism.

The term may also be applied to the practice of undressing or otherwise exposing a female partner to others, as well as to either the consensual posting of personal images of a female partner on the internet or to urging her to wear clothing which reveals her physical attractiveness to others — such as a microskirt, tight-fitting or see-through clothing, low-cut top, or minimal-coverage swimwear.
