 The current findings do suggest that for the majority of American men, pornography exposure (even at the highest levels assessed here) is not associated with high levels of sexual aggression…But among those at the highest “predisposing” risk level for sexual aggression (a little above 7% of the entire sample), those who are very frequent pornography users (about 12% of this high risk group) have sexual aggression levels approximately four times higher than their counterparts who do not very frequently consume pornography.
