Mainstream science still generally tells us that Porn is perfectly fine! "Go ahead 13 year olds!", they say.
When I started watching porn at 16, I had an intuitive feeling that it might be a bad idea. So I Googled: "Is porn healthy?", the answer I got was a resounding
"Yes! It's fine!".
For the next 5 years I watched porn whenever I felt like. In my early 20s, I had problems getting erections because of porn, which according to mainstream medicine is impossible! I was told it was being caused by "nervousness", (despite the fact that I wasn't nervous at all) I was told that porn induced ED was nothing but pseudoscience.
Basically, mainstream medicine and psychology has completely failed an entire generation on Porn.
Who are most negatively affected by porn? Young men. And that's precisely why nobody is doing anything to fix the problem. Nobody cares about young men.
