In reading the book "Garden of Purity for Men" he makes a huge deal about personal prayer, that is, prayer beside the regular daily prayer, and spending at least 30 minutes of it on this one issue, lust. And not just lust for other women, but women including one's wife. He says that when we lust for our wife we are not loving her or seeking her welfare, but rather our own. Lust, in general, is what he encourages the reader to address in prayer. That Hashem would remove it from him completely, and that he would be filled with love for his wife and not lust.
I can attest to the validity of a great deal of the author's insight from what has happened in my life since I have truly decided to fight, with pleading for Hashem's help in prayer, the evil inclination. I recommend everyone read this book. Clearly, this battle is not a simple and pleasant one, but as someone has told me, "you haven't resisted sin to the point of shedding blood have you."
I think, from my past experience, we, more times than not, do not take extreme measures concerning this sin. How serious are we about our personal holiness? What tools that Hashem has provided are we neglecting? I have spoken to some who say they don't have time to spend 30+ minutes in prayer. Really? Priorities must be considered. We put filters on, create, and keep the password ourselves. Is that really the wisest way to handle that? Surely, most on this site have someone they trust? Rabbi, friend, family, etc. Why not let them set the password and keep it? If we aren't able to get on a site, maybe it's Hashem's will? As I said, how serious is this to you. Are we willing to take extreme measures to guard our eyes and our personal holiness?
May Hashem assist us to do whatever it takes to triumph over this yetzer hara.
