Could you treat a porn addiction?

Yes: Most men get bored with this goofy stuff quickly. If you're missing out on the better things in life because of a focus on erotica, it's treatable. It'll be a combination of talking about what it means, and perhaps some medication. Mayo's reported Naltrexone stopping addiction cold, and i've heard of low doses of ssri's working. Get your freedom back by accepting treatment. Best wishes.
