Autoerotic asphyxiation is the induction of cerebral anoxia—a deficiency of oxygen in the brain—through self-applied suffocation methods while masturbating. This strange sexual practice is still an enigma for most of society.

It is estimated that between 500 and 1000 deaths occur annually in the United States from this dangerous type of masturbation. Most commonly performed by young adult males, it almost always remains a secret until they die accidentally.

Autoerotic asphyxiation interferes with the blood supply to the brain. The lack of blood, and therefore oxygen, to the brain can produce giddiness, exhilaration or a self-induced "high."

Many believe that the self-endangerment inherent in the technique enhances the person's sexual gratification. Autoerotic asphyxiation participants often use a rope, belt or another device to cause their asphyxiation.

Of course, the solitary thrills of asphyxiating oneself are short lived and self-endangering. Autoerotic asphyxiation also weakens one's self-control and judgment and sometimes results in accidental death.
