Nancy Houston, author of the book, "Love and Sex," talks about the dangerous addiction of pornography. Houston explains that God created sex to be a bonding experience between a husband and wife. When a person watches porn, he/she gets a rush of dopamine, which makes it addictive. It also damages the relationship center of the brain, called the prefrontal cortex. "Porn is often used to medicate pain," Houston says, "But there are deeper issues that usually need healing." A necessary first step to recovery is to bring our addiction out of the dark and into the light.
