The short podcast at this link gives some great perspective and advice on how to share your struggle with pornography with your spouse.

Here are a couple of points:

• Talk to someone “safe” first such as your pastor, a counselor or trusted friend
• It is better to tell your spouse than to be caught by them
• Honesty is the foundation of intimacy
• All of the gory details are not necessary
• Don’t unload on your spouse to ease your guilt, but to create openness and honesty
• Be prepared to receive their anger and don’t let that deter you from being honest
• Don’t wait for the perfect time – it will never arrive – it will always be awkward and difficult
