Sexual behavior activates the same 'reward system' circuitry in the brain as addictive drugs, such as cocaine and methamphetamines, which can result in self-reinforcing activity, or recurrent behaviors," Christman said.
"Internet pornography, specifically, has been shown to be a supernormal stimulus of this circuitry, which may be due to the ability to continuously and instantaneously self-select novel and more sexually arousing images," he added.
Watching too much internet porn can increase a person's "tolerance," the same as with narcotics, Christman explained. Regular porn watchers are less likely to respond to regular, real-world sexual activity, and must increasingly rely on pornography for release, he said.
