1. In addition to turning off the computer when getting close to bedtime, unplug it from the wall and disconnect the telephone/DSL wire. Why? Because it will give you time to think before moving the mouse to wake up your computer or to turn it on late at night.

2. Be prepared for some withdrawal symptoms, yet understand that this is going to be a normal reaction--deal with it.

3. Go to bed earlier than normal and snuggle with your wife and if tempted to get out of bed later--don't you dare!

4. Begin using your imagination more and do some fantasizing instead of relying upon porn scripts and action. (I gave up on X-rated videos way back when the scripts changed from lots of action climaxing in a man's or woman's climax to just lots and Lots and LOTS of action and seemingly no orgasm. BORING, Unfulfilling.

5. Begin consciously paying more attention to your wife/partner. Make it a priority. Instead of returning to the computer--return to your wife and make your own script.
+ Make her the leading lady, make you the leading man.

Firstly, good move for recognising you're not happy with your approach to porn and the effect you see it having on your relationship. I know where you're coming from. I had a porn addiction too and then decided to do something about. My situation at the time was slightly different. I'm sharing this in the hope it might give you an idea what changed for me and why.

Over a year ago I'd broken up from a long term relationship, among the reasons for the relationship failing were mismatched libidos. Mine was rampantly higher. I also watched porn, she was OK with this and sometimes we watched it together. After we broke up, I continued to watch porn regularly while I was single. Knocking one out was a little pick me up, once or twice a day. As I started dating again, invariably there were good and bad dates. Some lovely women and very nice times. But when it came to sex, my focus was always in the wrong place. Getting off. After a couple of months of dating, it became obvious, getting laid was more challenging with a higher failure rate than simply knocking one out at home with porn.

In the process of getting out of mild depression and improving my health, I also looked at why I was watching so much porn. Then I made an association that porn addiction was like a drink or drug addition. It was a crutch to deal with the depression. A quick, free and easy pick me up. Just like a drink, drugs or cigarettes etc.... When feeling down, due to loneliness or which ever negative emotion, got the better of me that day, I'd resort to a quick fix. Drink, smoke, porn etc. In fact, this cycle was self perpetuating. Like quitting smoking, it picked up negative connotations. In the case of porn, its not real, its a substitute. I was only knocking one out, because I wasn't getting laid. I'm not saying porn is wrong. The point is, my reasons for watching it at the time, were wrong. I was surprised that I went off porn. For the first time in my adult life, over 15 years, I didn't enjoy porn and stopped masturbating for months. My interaction with dates progressed when I stopped thinking with my balls and more with my brain.

Several months later, I'm a healthier happier person and in a fantastic relationship. We have a great sex life and also enjoy watching porn together. Now I enjoy it for a totally different reason. Its adds to our sex life, rather than substituting for the lack of one.

That's my story regarding porn addiction. I hope there are some lessons learnt there that may help you.
