Bullshit. Nobody knew what the “ED rates” in the general or younger population were before to begin with, so nobody can claim there has been “a pretty drastic increase”.
This should be pretty simple, you don’t need a “data scientist” to explain A/B tests to you: if you can’t claim that something has increased if you don’t know what it was before.
All that the sex-therapists and psychopopologists can claim is that they are seeing an increase in the number of younger men coming in to them with claims of ED. This could be due to a number of reasons, the main one being a reduction in the stigmatization of ED due to increased awareness (that it is fairly commonplace, even amongst young men), advertising of Viagra and associating ED with rich white successful older men who are using it to have affairs with younger women.
The writer brings up playboy and cave-paintings of naked women, but never explains what is the difference between a teenage boy masturbating 4 times a day to Playboy (or Archie comics) and a teenage boy masturbating 4 times a day to internet porn.
The bigger concern with porn is the effect it has on women’s self-image and sex-lives due to porn-addled men trying to impose their fantasies on their sex partners.
