Asphyxophilia is a sexual paraphilia in which an individual is aroused by or sexually interested in asphyxiation at the moment of orgasm. Typically, individuals that have this particular paraphilia enjoy being asphyxiated by another at the time of orgasm. It can involve self-asphyxiation during masturbation.
More About Asphyxophilia
An individual that has asphyxophilia finds pleasure in not being able to breathe, especially while climaxing. An individual can be asphyxiated by a partner choking, strangulation, or suffocation. This type of play is extremely dangerous because a lack of oxygen flow to the brain for extended periods of time can be damaging, and even cause death.
