“Who dies in youth and vigor, dies the best”. Alexander Pope
Autoerotic fatalities are deaths caused by unusual and risky introverted sexual practices such as self-bondage and autoerotic asphyxia. However, occasionally more strange forms of autoerotic death also occur. The most common causes of death in autoerotic fatalities are strangulation and hanging but autoerotic deaths have also resulted from other methods, including electrocution, sepsis after rupture of colon (from insertion of foreign bodies in the rectum), crushing injuries, and accidental self-impalement.
Autoeroticism is an extreme form of masturbation in which asphyxiating or choking is the pursuit of the physiological effects connected with decreased oxygen (blood) supply to the brain. Strangulation (which interferes with blood supply to the brain) is almost certainly more perilous than suffocation (cutting off air flow to the lungs by covering the nose and mouth). But, both can be lethal.
When the oxygen in the body drops, all these forms of behavior have a bigger possibility of affecting the heart by altering the rate, rhythm and contraction. Heart attacks are not unheard off after autoerotic activities.
The name of the game is to decrease blood flow to the brain, which is purported to intensify the sexual gratification. It is an exceedingly dangerous practice that results in many deaths each year.
