What % of guys have difficultly getting&maintaining an erection good enough for sexual intercourse?

Someone else made a post what % of guys are porn addicted.

But something I am more interested in is what % of guys suffer from PIED in any country that has unlimited high speed internet access? So this would be guys in any country that has unlimited high speed internet access from the age of 16 to 40 who suffer with erectile dysfunction or sexual dysfunction issues, I.e have issues getting and maintaining an erection good enough for sexual intercourse.

So what % of guys from the age of 16 to 40 in any country that have unlimited high speed internet access have difficultly getting or maintaining an erection good enough for sexual intercourse?

The reason why I say countries that have unlimited high speed internet access is because countries with restricted internet access or no internet access the majority of guys from these countries won't suffer with erectile dysfunction or sexual functioning issues.

In any country that has unlimited high speed internet access I would imagine there would be a high percentage of guys in these countries that would have sexual functioning issues. But I sometimes get the impression much less guys are suffering from these issues than what are suffering from these issues.
