Asphyxiation play, also known as breath control play or erotic asphyxiation, is the practice of intentionally restricting the flow of oxygen to the brain for sexual gratification. There are several ways to accomplish the oxygen restriction. They include hanging, using a plastic bag for suffocation, self-strangulation, chest compression, and specific gases or solvents.
When one person engages in asphyxiation play by themselves it is called autoerotic asphyxiation.
More About Asphyxiation Play
Asphyxiation play can pose a significant danger to participants especially when practicing alone. Autoerotic asphyxiation is particularly dangerous because there is no one to assist if the person who is being deprived of oxygen loses consciousness. Additionally as people engaging in asphyxiation play alone may create a complicated set-up for depriving themselves of oxygen, they may become incapable of releasing themselves.
This is a form of edge play.
