Neck fetishes are a sexual arousal by or sexual interest in the neck of another person. The neck is both a vulnerable and sensitive part of the body, making it both an erogenous zone and and an area that people may be drawn to. In addition, research has shown that humans emit pheromones from sweat glands in the armpits, making the neck a prime place to pick up those attractive scents. The neck is also full of nerve endings that are part of the peripheral nervous system, which is responsible for relaying sensory information throughout the body.
Neck fetish is closely related to throat fetish, which can include viewing the throat, touching and biting it, or even erotic asphyxiation. The anatomy of the throat, including the veins and voice box, are part of the appeal. Neck and throat fetishes are common in pornography.
