Studies have found that frequency of porn use correlates with depression, anxiety, stress, and social problems.

 

Even moderate porn use is correlated with shrunken grey matter in parts of the brain that oversee cognitive function.

There are clear differences in brain activity between patients who have compulsive sexual behavior and healthy volunteers.

 

“Sexual tastes are molded by an individual’s experiences and their culture…” –Norman Doidge, PhD

Porn use has been found to influence some users' sexual preferences, leaving them wanting what they've seen onscreen and significantly less satisfied with sex in real life. 

After being exposed to pornography, men reported being less satisfied with their partners’ physical appearance, sexual performance, and level of affection and express greater desire for sex without emotional involvement.

 

Among the effects of the use of pornography are an increased negative attitude toward women, decreased empathy for victims of sexual violence… and an increase in dominating and sexually imposing behavior.

A meta-analysis of 33 studies found that exposure to either nonviolent or violent porn increased behavioral aggression, including both violent fantasies and actual violent assaults.

The Department of Justice and the National Center for Missing and Exploited Children both recognize that pornography is an element that adds to the serious problem of sex trafficking.
