Hello Forgiveness, new member here. (Caution: I'm a Quaker.)
But one thing that has created a wedge between me and God is my addiction to porn.
That is a good and pertinent question.
Allow me, as a man who knows what porn addiction is like, to put in my 2 cents. Of course I can not know whether my experiences and point of view will be helpful to you, all I can do is offer my 2 cents.
I think you basically already answered your own question and already pinpointed the way out of the problem, namely the way out is to realize that it is an ADDICTION.
Now consider what addiction is. An addiction is something that has taken hold of you against your better judgment. Your conscious mind knows that it is not beneficial to you, but the "lower, animal part" of your brain is HOOKED. And is hooked so throroughly that despite the fact that your "better self" is crying out against it, still you can not free yourself of the addiction.
The thing to realize is that you (like everyone else) have this lower, "animal" part inside your brain. It is the "reptile brain", the part of the brain that mindlessly reacts to primal impulses. And part of the reptile brain of MEN is this vulnerability to porn, to the pure flesh of sexy women.
So given that, now realize the situation. There is this porn coming from outside, that against your better judgment is keeping you hooked. What this porn is doing, is it DELIBERATELY TARGETS that vulnerable spot in you. Porn is DELIBERATELY CONSTRUCTED to do this.
I think all teenage girls probably get to know this vulnerable spot in men pretty early on. A pretty girl only has to flash a thigh or lower the neckline to drive men completely nuts. This is a power that sexy women have over men, a power that is susceptible to being misused, not only by women themselves, but also by these agencies or companies (probably mostly run by men) who produce porn.
Individual women (of the evil kind) use this vulnerability in men to hook them and to manipulate them. But the women who do this, I am completely sure that these women are conscious that what they are doing is MANIPULATION. They are women who, having found this weak spot in men, are then going on and misusing it for the purpose of manipulation.
The companies that produce porn are using this same weak spot in men to do the same, namely to MANIPULATE you. In the case of porn it is for the purpose of commercial gain -- namely those ads that porn sites are permeated with. Your animal side is being misused to keep you hooked on the porn, and to keep you hooked at continuing to visit porn sites forever, because they have got you addicted.
Another key thing to realize is that LOVE is not SEX. With the word "Sex", I mean carnal lust (as in porn). And with the word "Love", I of course mean Christian Love, the Love that Jesus has told us about, the opposite of the mind-set of hatred and narcissism. Love for other people simply because they are also human beings, who like yourself also have this Spark of God inside them.
So now pause and reflect. On the one side we have carnal lust, which is of the flesh. On the one side we have Love, which is of the Spirit. Now the key thing that will get you out of the porn addiction is to discover for yourself that Love is much much better than carnal lust, including also that Love gives you A MUCH BETTER FEELING than carnal lust. This FEELING of Love will get you out of the addiction that porn has chained your animal brain to.
The feeling of Love is one of pure Light and Goodness, it will make your spirit soar, and it will also become an "addiction" but in a good way, an addiction to Goodness, an addiction with which your "higher self" is totally in accordance. The "addiction" to Love is the right way of being, in which there is no longer the conflict between the lower animal self and the "higher brain". Metaphorically speaking, you have found Paradise, but note that Paradise is first of all of the Spirit, more than of the flesh.
Compare this with the addiction to porn, where your "lower self" is in CONFLICT with your "higher self". You are all twisted up inside. The addiction that your lower self is chained to is not in accordance with the things your higher brain is craving.
One thing that helped me get out of porn addiction is to realize deeply that porn is manipulation, it is people DELIBERATELY TRYING to hook you. People who are so evil that they do not feel compunction in MISUSING this weak spot in men in order to make you into an addict and totally ruin your life, for the sole purpose of selling a few more ads. So therefore that is truly Evil. In porn, you are staring Evil in the face. Porn is what the Devil looks like. The Devil is alluring, is deliberately creating an alluring image, for the sole purpose of luring you in and trapping you. Creating an alluring external is what all manipulators and con men do. The very fact that it is so alluring to your animal brain, that it is images/videos that GRAB and HOOK your animal self despite your higher self protesting, that very fact itself directly and immediately tells you that it is the Devil. That carnal, animal brain alluringness, so deliberately wielded as a manipulative instrument, that very thing is exactly what the Devil looks like. The Devil does not look like a gruesome horned beast, but looks like porn.
And another word about women. I believe that good women will never misuse this weak spot in men. Good women, meaning women who are NOT manipulators, do not behave like porn starlets. Because behaving in that way is manipulation. And good women do not enjoy manipulating people (same as good men likewise do not enjoy manipulating people). The image of women in porn is totally twisted, and it is an image of women that is an artificial creation (like also the image of women in most modern films and tv series is twisted and artificial). Good women (Christian women) are looking not for porn addicts, but are looking for GOOD men, meaning men who have succeeded in coming away from addiction and consumerism and all that shit, men who have found the Spirit and who have found God, men who have found out that Love is not weakness but strength. Real life, the life that will give you fulfillment, is of the Spirit.
