I see your point, but when I was active in my "addiction" or whatever you want to call it, I tried to get help from a "professional" and was told that there was nothing wrong in my behavior.
I was spending close to 40 hours a week watching porn, I would skip school, work, time with family, and sleep to watch porn. I didn't want to watch porn, but couldn't stop.
Now I stopped and my life is so much better. And I am so glad that I didn't listen to that professional, and found real help.
