Autassassinophilia is a paraphilia or fetish where an individual becomes, is aroused, or finds sexual pleasure in the idea of and/or the actual risk of being killed. This can exist in conjunction with other fetishes that actually put the life at risk such as autoerotic asphyxiation. Some autassassinophiliacs derive pleasure from the act of planning their own deaths.
