"The autassassinophiliac, for Money, is more interested in his orgasm than in his death, resulting in a compulsion to 'stage manage the ''possibility'' rather than the ''actuality'' of his end at the hands of another person. The erotophonophiliac, on the other hand, is driven by the actualization of the other's death and – crucially – this other must be unaware of the would-be killer's intentions. These definitions, then, effectively preclude reciprocity and are constructed here in such a way as to prevent the possibility of consent. The sexologist, it seems, is incapable of imagining mutuality in this context. () The imagined pact is used here as an incentive to the would-be libertarian to support the suppression of paraphilia and the conversion of a death-related desire to a life-giving form."〔Lisa Downing, "Eros and Thanatos in European and American Sexology" in Kate Fisher, Sarah Toulalan (eds.)
