Gymnophobia is a fear (phobia) of nudity. Gymnophobics experience anxiety from nudity, even if they realize their fear is irrational. They may worry about seeing others naked or being seen naked, or both. Their fear may stem from a general anxiety about sexuality, from a fear that they are physically inferior, or from a fear that their nakedness leaves them exposed and unprotected.  The word "Gymnophobia" is derived from the Greek "gymnos" (naked).
