I never believed in the theory that porn directly causes ED

There are several studies that have found no correlation, what may happen is that young men may feel porn is bad. Then, they're led to believe porn causes ED, a self-fulfilling prophecy. Some report that after quitting porn, their erections got better, but is probably not because of porn. It's more likely that as they took on NoFap, they also improved other areas of their life, which in turn lowered anxiety, improved depression, self-esteem, confidence, etc.

Staying away from what they believe is evil and harming them, consequently, makes them feel better emotionally. Most young men who have issues, actually have performance anxiety/mental health issues. (something they'll refuse to accept) is much easier to believe the cause of your problem is some outside force, rather than inside you.

What may happen is the more porn you watch, the worse you may feel about sex, your own sexual prowess, comparing yourself to men with big penises who last forever, watching women you may never get in real life, etc.

So it may cause ED, not by desensitization, but rather by worsening your mental health, lowering self-esteem, causing depression, anxiety about your self-image, penis, sexual performance, etc. This is why some see improvements after quitting porn. It's not that porn itself caused ED, but rather the effect it can have on your mental health which then causes ED. Its your mental health that caused it, not porn.

Why is ED among young men more common than in decades? Yes, is because of porn, but also social media and high expectations for men. It's not that porn causes ED directly, but rather just like social media, it can worse self-esteem, depression, self image, more importantly, it can make you feel inadequate about your sexuality, you feel you're not as big as those porn actors, don't last as long, don't please as well, don't cum as much, not as muscular or ripped, that you can't get women like those, etc.

This is the reason why ED is more common now, is not because of porn but rather the internet as a whole making men feel inadequate for not being good-looking enough, jacked enough, sexually powerful enough, not having enough money, game, status, women, etc

Everywhere you turn, you see men excelling at everything on social media, you turn to porn and you see men who have bigger dicks, bigger loads, last longer, fuck women you would only get in your dreams, etc
