The effects of pornography on individuals or their intimate relationships depend on the type of pornography used and differ from person to person. Consumption of pornographic material is associated with negative and positive impacts. It has been studied particularly for associations with addiction as well as effects on the brain over time. Some literature reviews suggest that pornographic images and films can be addictive, articularly when combined with masturbation,[4] while others maintain that data remains inconclusive.[5][6][7][8][9] Other research has looked at pornographic material's relation to acts of sexual violence, with varying results.
