Sigh... I know all too well that of which you write! The "slippery slope" of porn is just as bad, if not worse than any drug addiction, in my (unfortunate) experience! The way I beat my addiction to drugs was to finally and fully realize all of the ways that my addiction had ruined my life, and all of the ways that my life would improve when I quit. Once I had done that it was almost entirely "smooth sailing." Your mind just doesn't go there anymore because every level and fiber of your being has learned that your new way of life is the only acceptable course of action for you in the future. You have finally "had it" with your old behaviors and realize the extend to which they have led you astray. I encourage you to stay strong and avoid those triggers - i.e., watching just one video, or even looking at a nude photo for even one second! Just refuse to consume porn in any form from this day hence and watch what happens! But remember, you must reach a state of complete conviction in the rectitude of your new life and utter disgust with your former habits. I hope you find these words to be helpful and wish you much luck!
