If you've become a slave to pornography, then you must understand that having anything tempting in your house is going to plunge you back into this sin.  Perhaps, at one time, you could watch an R rated movie that contained a nude scene and not been tempted.  But because of your addiction, you can't anymore.

All nudity and other sensual images must leave your home.  Files, magazines, movies, etc.,.  Nothing stays.  Even the ones that seem innocent but have provocative advertisements.

If you live with others, and can't control everything, then try to keep everything that tempts you in one spot-one that you won't visit, like your wife's closet.
