What do you think about porn addiction?

What do you think about porn addiction? One source defines it as "a psychological addiction to, or dependence upon, pornography, theoretically characterized by obsessive viewing, reading, and thinking about pornography and sexual themes to the detriment of other areas of one's life." I believe that porn addiction is when a person is completely taken over with the need to use various types of pornographic materials (film, internet sites, books, etc.) to arouse, stimulate, and satisfy their own sexual desires. I am Overcomer who has overcome porn addiction and make a point to strive to stay healthy through my practice of Christianity, being open with my wife and my brotherhood of accountability, and being honest with myself about what forms of media (tv, music, reading materials, movies etc.), and conversations affect me.
I am wondering... what do you think about porn addiction? Do you believe you can be healed from it? Is it really a problem? Do black people get addicted porn? Is the addiction a need for intimacy or just a moment of fun gone out of control?
Your thoughts....
