According to psychologist Dr. Juli Slattery, author of “Finding the Hero in your Husband”, there are similarities between what happens to a man when he views pornography and what happens to a woman when she reads a romance novel.
“There is a neurochemical element with men and visual porn, but an emotional element with women and these novels,” she wrote.
Men are very visual, and viewing pornography produces a euphoric drug in the body. This drug is the reason pornography becomes addictive. When the natural high wears off, a man will crash and feel depressed (as happens with any drug) and crave another hit.
