This video gives an introduction to the science of pornography addiction. It explains that porn can act just like any other drug. It does this by hijacking our reward system. Prolonged exposure then increases tolerance. A compulsion to use, as well as withdrawal symptoms, can be the result. Porn can even mold our tastes and desires. Pornography addiction can make us lose interest in real mates, who pale in comparison.
The video makes it clear that pornography has some profound consequences for our brain and our sex lives. The good news is that the negative effects of excessive and long-term use of pornography are reversible.
