Modesty
When modesty is taken beyond what is normal, it is called prudishness. Gymnophobia is a fear of being naked where it is normal, such as a shower room in school. Exhibitionism is the act or urge to expose the genitals to strangers, a mental disorder that affects 2-4 percent of men. Other public exposure of the body, such as streaking, are not exhibitionism but an alternative social norm for celebration or protest.
