They aren’t saying that “no one is nine inches.” They’re saying that no one is nine inches and in a situation where the partner doesn’t realize that a nine inch dick is massive and not the norm. They didn’t phrase it well, but that’s what they are meaning.

Edit: They just edited a lot of the comment to confirm that they meant to say more or less how I interpreted it.
