Jan Sluyters - Nude in front of Mirror, 1922.
Nudity in art is, a specially in combination with a mirrior, a well knowned form of the classic game of voyeurism and exhibitionism. Nudity in art is much more then art pour art.
Voyeurism is the sexual interest in or practice of spying on people engaged in intimate behaviors, such as undressing, sexual activity, or other actions usually considered to be of a private nature.
Exhibitionism is the act of exposing in a public or semi-public context those parts of one’s body that are not normally exposed – for example, the breasts, genitals or buttocks. The practice may arise from a desire or compulsion to expose themselves in such a manner to groups of friends or acquaintances, or to strangers for their amusement or sexual satisfaction or to shock the bystander.
As a artist you have to make a living and to sell your work.
