You end up with guys with ed where a woman having normal sex may not even do it for them.

That's the case for men who already have an active sex life while getting addicted to porn. Sex addicts. A virgin who's never had sex before will most definitely not have problems getting aroused if he or she finally gets some. If there'll be problems it'll because of nervousness which isn't anything new or unusual.

But yes a porn addiction will fuck you up like every other addiction will.

We've always had virgins and we didn't have porn for most of history and yet guys managed and I would think better then now.

Porn has little to do with it. The relationship between men and women is completely messed up but not because of porn but because of social media and other far more damaging factors than porn.

But porn is generally extremely harmful to kids. Not adults though.

There should be a solution without porn.

Like I already stated porn isn't a solution. Porn and masturbation is incapable of being a substitute for physical human contact. Porn is if anything a bandaid.

Custom porn with what ever you want, where you can have actual conversations may be humanity's last invention.

Which shows that men (and women) seek human(-like) interaction.

At this point only the very religious societies survive.

Not because they don't have access to porn though but because the 'natural order' of human society is still intact.
