Nudity
People wear different amounts of clothing in private places than in public. Semi-public nudity may be necessary, such as when changing clothes or showering after work or exercise. Usual behavior when nude with others include respect for personal space and the separation of genders. In the 21st century, this everyday, non-sexual nudity has become uncomfortable. Changing ideas of gender and sexuality threaten the idea of separating the sexes. Digital photography threatens keeping any behavior private. At the same time, modern media contain more images of sexualized nudity. There are fewer ways to learn that nudity is not always sexual. There are fewer places to see ordinary people naked and learn what is normal.
