Ok I need help guys...

I lost my virginity around 9-10 years old. I've been hooked since. I can't ever remember porn not being part of my life. When I was 19 I started working as a bartender in a strip club. My life changed a bit a couple years ago and I started dating a chick who was too good for me. We broke up and that night I went out and slept with another chick. Thats when I realized something was wrong with me. It was the first time I had felt guilty about sleeping with a woman. Of course I've slept around since then but theres now this guilt with it and I believe its potentially screwed up what I would have had with wife. Now I feel like such shit when I look at porn, sleep around, or if I'm not doing those I'm jerking off but ef me I haven't yet been able to make it more than a few days. Sometimes a week, once in a great while a month...but longer? Never. Its like I'm almost afraid to totally let go just because its been here for so long. I've wanted to quit but failed. I need help. How do you quit this brutal stuff?
