If I had learned this sooner, it wouldn’t have taken me ten years to win my battle with pornography:

Imagine that you were overweight and you absolutedly loved brownies.  You know you need to lose weight and really want to be healthy so you decide that you are not going to eat any more brownies.  How successful do you think you would be if you constantly had fresh baked brownies in the house?  You might resist eating them some days, but on other days the smell would just be too much to overcome.  That is how I was for a long time in my struggle with pornography.  I wanted to quit, but I never got rid of all of the garbage that surrounds us every day and so there would be days I could resist it and others when I gave in.

You are being bombarded with things that are going to fill you with desire … things you see on TV, movies, and magazines.  Even just seeing an attractive girl can cause your mind to wander.  All of this is like having those freshly baked brownies in your house — you are going to fail unless you can control your thoughts and limit what you see.  My wife and I made the choice to shut off our cable about a year back and I also avoid movies that I know are going to cause lustful desire.  I am also very aware of what I think — I had always in the past just tried to avoid the actual act of viewing the pornography, but I never tried to limit what I visualized in my mind during the day.  Now when I see an attractive woman or remember a picture or video that I had seen online I immediately redirect my thoughts and don’t let my mind dwell on the lustful things.  It takes some time, but if you can cut out the garbage that comes in from the media and if you can stop dwelling on lustful things then you will find it much easier to resist the draw to pornography.
