The narratives of individuals using child sexual exploitation material (CSEM) highlight the individual and unconscious functions of this type of sexual offense. Fluid cycles of projection into and identification with the children in the imagery were evident, as were marked differences in the intensity and exclusivity of pedophilic sexual preference. Anger was a common trigger, but conscious awareness of any associated hostilities toward the child in the imagery was vigorously defended against. The Internet, the now dominant context of child sexual abuse, offers a distinct type of environment, on the porous boundary between the internal and the external, that seems to encourage regression to early, varied paraphilic sexuality and part-object relations. Interactions in online forums facilitated the projection of pedophilic interests and sadistic impulses into other users. Broad empirical findings on the characteristics of those who use CSEM, coupled with this study and clinical experience, suggest that many who engage in this activity have an essentially neurotic structure.
