Some things are so obviously true that only a team of academics could convince themselves otherwise.

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 dare you to do this with Israel.

I'll probably be flagged/banned for even suggesting it.
