Dear Oneday -
I have to say that I agree with Laagvokeles completely. And that's a first.
Please entertain the possibility that this may not be the best place for you. It is a generally agreed fact that putting this struggle on your mind - even for the best and most l'shem Shomayim reasons - is still struggling with a dirty, disgusting and smelly enemy. If a smelly homeless guy would fall on you, would you hold hime and wrestle with him to get him down to the ground and beat him real good - or would you just try to push him off of you? Seriously. Which would you do?
Same with the menuval. Lust thoughts are stinky and smelly, covered with spit and excrement. OK, in the heat of the moment you consider them beautiful and the more porn you look at the more we are all fooled that it really is very pretty. But it is not. It is ugly and ruins everything.
So why would you grapple with it so? Why wrestle it to the ground? The Kitzur gives very good advice indeed when it says "run from it like a young dear", and Chaza"l are telling the truth that the main way to be saved from the YH is to run from it "like one who runs from fire". It cannot be 'dealt with', it cannot be struggled with. You need to be humble, smart, and run like hell. (oops)
You need to get your focus on
anything else other than fighting and struggling with lust. Laag is right. What happened to basketball? Where is your chevrah? You are young and you have plenty of fun things to do and explore rather than the seedy and smelly dirty world of porn. It is run by smelly money-grubbers who use sick women to make money, and everyone in the industry is made sicker every day. Daven for them one time and then abandon them to be taken care of by Hashem, who has a good plan for everybody. verachamov al kol ma'asov. It and they are none of your business.
I live without it just fine, I promise you. It does nothing for anyone's marriage, and it destroys everyone's manhood rather than building it. It separates people rather than connecting them. All this because it is a private experience that draws you and me deeper into ourselves and makes everyone else into props rather than real people.
And the more you put it one your mind, the more it will be there.
You know what I am talking about, I believe.
Now go to the beis hamidrash and then to the ball field, do mayseh chessed as much as possible to help people - not to use them to do your selfish mitzvos and get your olam haba (to heck with olam haba - its Hashem's business, not yours), focus on being useful to others and yourself, and get busy with your real friends. Ignore the fake friends on paper and the computer screen and get a real decent life - leave the big lust struggles to the tzaddikim like Laag (and me).
