I find masturbation and porn to be perfectly fine. I am the stereotypical basement dwelling, NEET loser you would imagine in your deepest wagecuck fantasies, but porn and a generally high libido is a symptom not a cause, if related at all.
IMO a lot of the porn-bad, nofap, coomer wojak broscience is a form of IDPOL for losers, so low in the social status pyramid that they need to invent their own losers-of-losers to have any claim to virtue in normie circles. It relates to porn because that's about the only way they can compare themselves with normies and not be squarely placed at the base, and this is only because porn and masturbation is a seldom discussed still somewhat taboo thing where no one is going to disparage their claims let alone encourage them to dive deeper into the topic. So claims to virtue by abstinence go undisputed, if looked at sideways like the weirdo you are.
Obviously pleasure seeking can be a detrimental thing, but porn is not any more inherently wrong than watching a tear jerker, anime or whatever other indulgence some loser in denial identifies as the one abstinence that absolves them from such status.
