The primary purpose of this project is to study the correlation between exposure to sexually-explicit materials and sexual offending. A thorough literature review has been conducted. The analyses include the definitions and history of sexual deviancy and paraphilia, a review of existing research that examines the complex relationship between said materials and criminal behavior, methods individuals use to access sexually-explicit materials, and case studies of individuals whose behavior is relevant to the purposes of this study. There does not appear to be a causal relationship between these two factors. However, there is an intricate, interrelated dynamic between the two that is worth examining more thoroughly. Further research should study the timeline in which sexual offenders first consumed sexually-explicit material, as well as the genesis of their sexually-deviant behaviors. This may lead to a clearer comprehension of their psychosexual criminality. Further understanding will hopefully lead to improved policies proposed by law makers, refined prevention/intervention strategies by law enforcement, and more effective rehabilitative methods for offenders.
