A relationship exists between frequent pornography consumption and sexually aggressive behavior. This relationship is especially strong for those with the highest "predisposing" risk level for sexual aggression. Those who are at high risk for sexual aggression and who frequently consume pornography have sexual aggression levels that are four times higher than those who do not consume pornography frequently.

The relationship between violence and pornography should not be brushed under the rug.
