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.
More About Neck Fetish
Neck and throat fetishes are usually focused on women's necks. The acts involved in neck and throat fetish play include aspects for dominance and submission. Particularly because the neck is a vulnerable area, submitting to a neck fetishist can increase that sense of vulnerability.
In many cultures, female necks are adorned or decorated with scarves and jewelry, so some neck fetishists say the neck is akin to a body that can be undressed.
