Nudity, or nakedness, is the state of wearing no clothing. The wearing of clothing is a predominantly human characteristic arising from functional needs such as protection from the elements and from cold temperatures, after the loss of body hair, and migration to colder regions. The amount of clothing worn depends on functional considerations, such as a need for warmth, as well as social circumstances. In some situations, a minimum amount of clothing or none at all may be considered socially acceptable, while in others much more clothing may be expected. Social considerations involve cultural issues of modesty, subjective decency and social norms, besides other considerations, and these may depend on the context. There may also be legal considerations.

"Full nudity" refers to complete nudity, while "partial nudity" refers to less than full nudity, with parts of the body covered in some manner. The term "partial nudity" is sometimes used to refer to exposure of skin beyond what the person using the expression considers to be within the limits of modesty. If the exposure is within the standards of modesty of a given culture and setting (e.g. wearing a bikini at a non-nude beach), terms such as nudity, partial or otherwise, are not normally used. If however, the degree of exposure exceeds the cultural norms of the setting, or if the activity or setting includes nudity as an understood part of its function, such as a nude beach, terminology relating to nudity and degrees thereof are typically used. Toplessness is regarded by most people as partial nudity.

"Full frontal nudity" describes a state of full nudity with the subject facing towards the viewer, with the whole front of the body exposed, including intimate parts such as a man's penis or woman's vulva. "Partial frontal nudity" typically only refers to the exposure of the breasts. "Non-frontal nudity" describes nudity where the whole back side of the body, including the buttocks, is exposed, or a side-view from any other direction.

There is no universal cure for genophobia. Some ways of coping with or treating anxiety issues is to see a psychiatrist, psychologist, or licensed counselor for therapy. Some people experiencing pain during sex may visit their doctor or gynecologist. Medicine may also be prescribed to treat the anxiety brought on by the phobia.

Genophobia or coitophobia is the physical or psychological fear of sexual relations or sexual intercourse. The word comes from the Greek nouns γένος "genos", meaning "offspring," and φόβος "phobos", meaning "fear." This word is also formed from the Greek noun "phobos" and the term coitus, referring to the act of copulation in which a male reproductive organ penetrates a female reproductive tract. The term erotophobia can also be used when describing genophobia. It comes from the name of the Greek god of erotic love, Eros. Genophobia can induce panic and fear in individuals, much like panic attacks. People who suffer from the phobia can be intensely affected by attempted sexual contact or just the thought of it. The extreme fear can lead to trouble in romantic relationships. Those afflicted by genophobia may stay away from getting involved in relationships to avoid the possibility of intimacy. This can lead to feelings of loneliness. Genophobic people may also feel lonely because they may feel embarrassed or ashamed of their personal fears.
