There have been a number of studies by various governments around the world on the effects of media upon sexual acting out that have shown that there is no relationship between pornography consumption and sexually acting out. There is a United States government study on violence in the media and engaging in violence that has had the same result. It seems as thought there is a barrier within some people about acting out their desires/interests and others who will violate that proclivity. We know very little about that difference.
