I was going to say that you won't have any luck. Porn Addiction is not recognized as an actual disorder. It's not even mentioned in the up-to-date edition of the DSM manual. That, and nearly all major scientific and psychological journals and studies that have conducted research on porn addiction have found little evidence to support the argument of porn addiction.
Who cares if it isn't in the DSM? Any good psychologist or psychiatrist will help a patient with this problem. Therapy is a huge weapon in this fight, and I urge you to follow through with it.
