You and I both know that filters are no long term solution and there will be a day when there will be a computer without one...but that is a bridge you will cross then. In the mean time, this is now, and having a filter is something that helps us remember we have no business lust-dredging on the internet. So please forgive my impertinence, but:
Why don't you put a filter (like K-9) on the home computer? Is it resistance from the parents, wife, or someone else (I do not know if you are 12 or 30, married or not)? Is it your
own reluctance to insist a filter be put on it that is sabotaging you? Hey, this is important to you, no? Let them know you want a filter and 'blame' it on the psak of many poskim. No big deal.
*****************
But your problem does not sound like addiction to me. Does it to you?
You have a yetzer hora, you like how orgasm feels when you masturbate, and you have the body parts to do it. I don't understand why you seem surprised.
This is what Hashem created Teshuvah for.
Addiction and recovery are not aveiros and Teshuvah.
Guys masturbate cuz it feels good and have wet dreams because sex - whether it is right or wrong - feels nice. You are not the only one. Yaakov Avinu calls Reuven "Reishis Oni" because as Chaza"l tel us, he did not have a wet dream and Reuven was from his 'first' sperm. The Novi Eliyahu is praised as a holy man by the Shunamis lady because, as Chaza"l tell us, she washed his sheets and never noticed sperm on them.
These people would never have sunk so low as we do, to masturbate themselves, and that is not my point. My point is that having no wet dreams is an achievement worthy of the greatest of prophets from 3000 years ago.
On
our level, the struggle with sex with ourselves (masturbation) is quite understandable, if we are just humble enough to admit it to ourselves. And with Hashems help (He loves you), you
can find a trusted and understanding Rebbi or friend here or (far better) in person to talk with about your challenge in detail and on a weekly or even daily basis. That's OK.
But going it alone and in total secrecy is the way we isolate and keeps this real struggle much bigger and deeper that it deserves to be. There will always be religious zealots who want you to make never masturbating again the entire focus of your life. They often cite kabalistic and hashkafic reasons to do that. I hope you do not twist yourself into a Gordian knot by listening to that yetzer hora. It is based on pride - the expectation that we should measure up to people we cannot even begin to relate to.
Ba'asher Hoo shom is the key to Teshuvah - where you really are, who you really are. Hashem is in
reality, not fantasy -
not even religious fantasy. I believe you understand what I mean.
Torah is like water. It is meant to flow down to the lowest spot. It does not flow up. Let yourself be what you are, and find G-d right there. Shock at 'still having this struggle' is unreasonable. Go and get the help you really need.
That help will not come in a book, nor a sefer, nor in thinking about it and crying. It will come in opening up to real people. This is a real, live problem and isolation is its main protective layer.
Hatzlocha!!
