ttzyk,
I love your honesty. I too love masturbating, it feels great. I am not going to lie. I think all of us on here really enjoyed doing it. Indulging in fantasies and getting that release is a great physical pleasure.
It is very hard to give up and I remember when I started the 90 day I was waiting for the day that I would fall, because I knew I would not be successful in stopping, I just did not have it in me. It came eventually, 6 months later. But by then I saw how much better life was when I was not indulging in porn and masturbation every day. So I got back up and started again.
I didn't learn why I wanted to give up and get sober until after I was clean for some time. So my advice to you is just start but with no deadline. Go day be day, one day at a time, and see how far you go. If you really feel the need for a celebratory masturbation at some point, I pray that you have found a better way to celebrate than that by the time you get there.
