Why is Porn Addictive?

Porn is addictive for the same reason that many drugs are addictive. Neuroscientist Dr. William Struthers explains how the brain reacts to viewing pornography repeatedly:

As men fall deeper into the mental habit of fixating on these images, the exposure to them creates neural pathways. Like a path is created in the woods with each successive hiker, so do the neural paths set the course for the next time an erotic image is viewed. Over time these neural paths become wider as they are repeatedly traveled with each exposure to pornography. They become the automatic pathway through which interactions with women are routed. The neural circuitry anchors this process solidly in the brain. With each lingering stare, pornography deepens the Grand Canyon-like gorge in the brain through with images of women are destined to flow. (Wired for Intimacy, p.85)

In my interview with Dr. Struthers, he explained what hormones and neurotransmitters are involved in porn addiction. 

Testosterone

This is a gonadal hormone (produced in the testis) involved in many processes in the body. One of them is the male sexual drive. Testosterone drives a man’s interest in sex. Mentally fantasizing triggers a reflexive response in the body to release testosterone, and the more one does this, the “wave” of testosterone continues to build. Men experience this as an intense and growing desire for sexual release.

This wave of testosterone will occur if a man is thinking about or interacting with his wife, but it also happens when a man is staring at other women or a pornographic image.  Continue at Covenant Eyes
