In most societies and cultures, human nudity is often associated with sexuality. Many people are sexually attracted to nudity, which they find to be erotic and sexually arousing. Some people employ their nudity to sexually attract a mate or sexual partner or as a form of flirting.
Nudity is one facet, and at times a very important facet, in the expression of feelings in intimate relationships in which there is physical or emotional intimacy. Physical intimacy is characterized by romantic or passionate love and attachment, or sexual activity.
Some people have a compulsive desire to express such emotions and to express those emotions without clothing. Some people may experience erotic and sexual pleasure in seeing their partner in the nude, or to be seen nude by the partner. Some people also experience similar pleasure from seeing other people in the nude, and being seen in the nude by others, not necessarily their immediate partner.
Some cultures equate nudity with sexuality, but that is not always the case. Historically, nudity has been practiced in some cultures without any necessary association with sexuality. Nudity can exist in non-sexual social contexts, such as naturism and figure drawing; it can be sensual through non-sexual contexts, such as erotic performance art and striptease; or in overt sexualized contexts, as in the case of pornography.
