Porn is not just porn, for the guy quitting, it is anything that triggers a dopamine rush. And when quitting, a lot of things will. Be on your guard.
Porn is seeing porn, it is watching it, it is thinking about it, it is imagining it, it is remembering it, it is thinking about it while MOing even if you are not actually watching it, it is PMOing, it is fantasizing, it is edging while watching or thinking about it, it is having actual sex while thinking of porn, it is porn substitutes, any hypersexualized imagery or thought of that. Porn can be strictly in the brain, or it can be in hard copy, it can be on computers, televisions, and on smart phones, as in apps. Porn is phone sex. Porn is engaging any thought of unreal sex. Porn is chat rooms. Porn is sex toys. For one guy in this forum, porn is a cock ring. Porn does not have to be visual, it can be strictly audio. Why do you think "screaming" is a common porn category? Recent studies indicate "sex sounds" can cause arousal, i.e., a dopamine release. Porn can be literature about sex. Porn can be cartoons, drawings, hentai. Porn does not have to be on porn sites, it can be found on Facebook, Craigslist, Youtube, etc. It can be found on commercial retail sites; Sears, Target, Walmart. For me, when I first started quitting, I told myself I was making progress because I moved from very hardcore stuff to Google images, where I searched vanilla nudes. Bikini pics triggered me. Lingerie models triggered me. Hooters girls triggered me. Just girls on the street triggered me if I let them. I consciously have decided not to let hypersexualized images linger in my head. Before, I was not making progress, I was still feeding my dopamine fix. You have to avoid your triggers, not flirt with them. Let me say this again--you have to avoid your triggers, not flirt with them. Your triggers are not going to be merely the hardcore stuff you are trying to quit watching, they will be much softer stuff than can pop out on you from benign sites like Yahoo, Craigslist, Google. You have know that in advance and plan on avoiding them. You have to get your dopamine levels back down. That will take time. Plan on 90 days, it may not take that long, but plan on that. Better to plan too long than too short. Rebooting requires a total absence of porn in your head. If you are walking down the street in the middle of the day thinking about porn, you are using porn, so find something else to pop in your head if that situation occurs. As in now. What are you planning on thinking to distract yourself when the inevitable "visions" pop in there? I think "no no no no no no no", and I keep thinking that until it goes away. Sometimes I click my tongue on the roof of my mouth. It does not take a lot and the purpose of this exercise it to stop a vision of 1/2 second from becoming an indulgence, a fantasy, of minutes, which will spike your dopamine level. You want to avoid that.
For addicts, especially when we first quit, and we have not brought our dopamine levels back down, our brains look for any trigger it can find, even things society does not define as porn.
Be aware of this, and avoid those triggers.
