Relevant magazine posted a former porn addict's confession here. The article, by John Buckingham, begins with this:
"Hi, my name is John, and I was a sex addict. I am also a believer in the death and resurrection of Jesus Christ and am married to an amazing and beautiful woman of God."
John's wife Rachel writes a follow-up here. She describes her reaction when her husband told her about his porn addiction.
"Within minutes, the foundation of our marriage was shaken. The trust we had built was destroyed. I no longer felt safe or loved. I was suddenly bombarded with lies—he doesn't find me attractive; it's my fault he strayed; I'm not beautiful; I'm not sexy; I am a horrible wife; I'm a failure; he is stuck with me; he doesn't love me ... these seemed to instantly go from ridiculous to quite possibly true."
