Hi friend, there is not a general consensus I'm afraid in the mental health department, and the amount of damage it generates, but it's there, the seek of supranormal stimuli and then the act of fapping to that stimuli to achieve an orgasm is indeed rewiring how your brain works, making you unable to concentrate, always seeking that dopamine rush and falling more and more inside of porn, always looking more shocking videos than before, because like with any drug, we become addicted and obligated to up the dosage.
If you cut out the chain and stop fapping behavior your brain slowly through surely will start the healing process, the one that makes you have brain fog and want to watch porn and fap all the time, those neural highways developed with the years will cease to exist in due time, but you gotta find balance in life, and joy in things that aren't porn, don't ask me how though I'm figuring that out myself.
