While there are others which claim there may be a weak link but still inconclusive:

- Pornography and Sexual Dysfunction: Is There Any Relationship?: https://link.springer.com/article/10.1007/s11930-023-00380-z

You say that but then link to a broad meta study that is conclusive that no strong relationship exists .. ie. there's no signal, just noise.

    Recent Findings: Twenty-eight studies directly related to the issue were identified, and another 23 studies were used as supporting material

    Summary: Claims of a strong relationship between pornography use and sexual dysfunction are generally unfounded, both by the findings of studies and/or by misinterpretations of them.

The main factor that I'm aware of is hyperstimulation. There's the mental effect from exposure to increasingly extreme and perverse categories of porn (pedophilia, AGP/sissy, interracial, bestiality, BDSM, etc) "numbing" porn-sick men to healthy sexual stimuli, as well as the physical effects of overstimulation in the form of "death grip syndrome" where these men become so accustomed to their hands that nothing else can do the job.

These factors, combined with the lowered confidence and shame associated with porn addiction, intuitively also lead to anxiety-related performance issues.

I also think your list is weird. Pedophilia is dimetral to a normal relationship.

Why interracial? If you are in such a relationship, you can live it out.

Ah, yes. I feel it must be so, so no need for evidence and of course any evidence that exists otherwise must be false.

That, and watching too many movies from 1964 on the intertubes.
