Its Gotten way out of control

Hello everyone,

My name is Reed, I have been addicted to porn now for 12 years. I started when I was 13 and have been struggling with it ever since. I started with magazines that my mom had around the house then moved to the victoria secret mags. it started to increase to more intense fetishes when I was about 16. Being a big guy I always looked older than what I actually was. I was able to buy porn mags and get away with it. turning 18 is when I went to my first adult book store. I went in and this is when things really got out of control. I found the buy 3 for 20 and went down hill from there. I couldnt go a dey let alone maybe a couple of hours without touching myself. I have started to get into some bad sides of the fetish and it is time to stop. I have a fiance that I have been with for 3 years but unfortunetly this has put a rather large gap in our relationship. I want to be with her for the rest of my life and I know that she is the one. She has delt with this time and time again and I need to stop or our relationship will. I fail time and time again and I am not sure how to stop. I have seeked support groups and they always seem to highten my hunger for porn. I have tried books and those have not seem to work either. This is the first time I have ever been on a site like this, I need all the help I can get and any advice you can give would be appreciated. I look forward to reading your post and any help you can provide.
