Kudos to you man! We're proud of you for your strength and courage.
Recovering from any form of addiction is tough. I happen to be a recovering porn addict, and while I'm not saying they might be the same or anything, I understand relapse all too well. If you ever feel like relapsing or anything, find somebody you know cares, and tell them so they can give you a sound earful.
Btw to those that don't know, porn (not masturbation) is actually a bad thing if done in excess in the long run.
