I tried to masturbate without porn after a long time for curiosity if I was capable and for monitoring the POIS in that case and I found a strange thing: the POIS without porn give me much brain fog but little anxiety and depression while porn give less brain fog but much more depression and anxiety, I can't say this for sure because I will need more tests but it's not the first time that I noted this.
I was thinking that was about the different levels of dopamine in the pre orgasmic phase but I'm not sure.
I never had an orgasm with a woman because the only two times I had sex I don't reached orgasm but I am curious if the POIS could have different levels of symptoms in that case, maybe the more brain fog with pornless masturbation could be attribuited to more imagining or such.
In my ignorance I noted that the symptoms that POIS give me resemble to the shortage of dopamin and serotonin neurotransmitters, I am more and more convinced that cognitive POIS is a withdrawal syndrome from opioid receptors released with orgasm, indeed if I have another orgasm the symptoms go away and return after twenty minutes like a withdrawal syndrome from an addictive drug.
