In your wikipedia quote, replace the word “porn” with “subliminals” and you get the basic principle. 
The pathways don’t ever go away once created (barring extensive brain damage), but when you stop using them they start to get weaker. If you imagine active pathways as being lit up in the brain, the unused ones go dark over time. With some effort you can still find them and fall back into that habit (which is why addicts never really stop being addicts), but the darker they get, the harder it becomes.
TL;DR An interesting lecture on porn...
It’s a funny thing, porn’s influence on the brain. In a great support of the poly-amorous male, it turns out the male brain doesn’t like it when the sex-partner is always the same. When having/watching sex with the same woman, it will take longer and longer for the man to become/stay aroused and to have an orgasm. As long as the female partner changes, this stays relatively the same (look up the Coolidge-effect). I keep trying to explain to my girlfriends that’s just how I’m wired, but most show me little understanding.
Anyways, since the brain doesn’t really notice much difference between a real-life partner and the video on the screen, it will release dopamine every single time we watch a new video.
Furthermore, it starts to believe that all those women are yours to play with, which causes our primal hunter’s instinct to rewire itself. Constant porn becomes the new comfort zone. It leads to the desire to be isolated, to voyeurism and a constant need for new videos.
The next rewiring is to move away from the need to touch people, to date, to release and process pheromones, to interact and to experience an emotional connection.
Next, the constant flood of dopamine starts creating Delta-FosB in the brain which triggers the brain to start craving more porn. Over time, this will numb the pleasure response (not just of sex, but almost every common thing that should make us feel happy), making the brain excited by porn yet bored by many other things, and make our willpower weaker because of the changes in the frontal cortex. And the addiction is born. This by the way, is not exclusive to porn addiction, but to all addictions. Too much of a good thing is still too much, I guess.
Finally, in the case of porn addiction (scientifically known as arousal addiction), the changes in the brain cause a numbness which over time causes weaker arousal signals to be sent to the genitals, leading to the scary moment when you can’t get it up anymore. First, porn becomes less interesting, then libido starts dropping, and finally you won’t get it up. This is called addiction desensitization.
Fortunately, the very principle in my first paragraph of this post of turning off unused pathways and using new ones can reverse the effects including (in the case of hardcore addicts) anxiety, loss of focus and memory retention as well as trigger previous levels of productivity and the natural instincts to go out and meet new people.
Something of note is that the recovery time is longer for people that have watched a large variety of porn as well as for those that have started watching porn during their teen years when the brain was developing rapidly and building very long-term habits. Hence it can take up to 6 months to fully recover.
Researchers attempting to study the difference between the porn watchers and the non-porn watchers have run into some issues, as almost every male above the age of 10 is regularly watching Internet porn, so there’s a great lack of a control group.
Fortunately the brain has a remarkable capacity to change according to the needs of its owner.
Most of the SubClub subliminals contain scripting that works in an opposite way, creating neural pathways that make porn boring and personal growth and relationships interesting. So they will over time darken the pathways leading to watching porn and brighten those leading to social and physical interaction. If you support them by doing your best to stay away from porn, the rewiring goes faster.
My own experience? First, I went from basic porn to more artful porn, clips that were directed well, took place in beautiful settings and were more like lovemaking than f*cking. Nowadays, I can look at a thumbnail and think “Hmm, that looks nice” but never get around to watching it because the impulse to do so simply doesn’t trigger anymore. Same goes for “self-service” without the use of videos. On the other hand, women have become increasingly interesting to me.
