Well over half of DPWs have felt this pathological attraction since childhood, as typical in paraphilias. "The Amelotatist" (see References) found that 75 percent of its sample of 195 were aware of the attraction by age fifteen. Those attracted often cherish early memories of a sexuoerotic tragedy (a "first sighting") involving an object of their future attention, often an older member of the opposite sex, as stereotypical in paraphilic etiology. About a quarter report discovering the paraphilia in puberty and a few in maturity.
