Porn’s first major blow decouples sex entirely from the communication of intimacy. Over time, sexual intensity replaces intimacy as the man’s primary focus. This is where significant damage to our hard-wiring begins.
If your hard-wiring is normal, as God created it, your focus is not on you but on your wife and her pleasure, and all your orgasms happen with her. Because of that, you associate your orgasms with your wife: her kiss, her scent, her body. Because of that reinforcement, that is what will turn you on over time and will keep you fascinated with the wife of your youth.
May your fountain be blessed, and may you rejoice in the wife of your youth. A loving doe, a graceful deer–may her breasts satisfy you always, may you ever by captivated by her love. (PROVERBS 5:18-19)
