Oh, I know, and to some extent I agree. To me, it's one of these author idiosyncrasies; it makes me roll my eyes a little, but all in all it doesn't stop me from enjoying the story.
But no writer before (or since, really) did (or has done) so to such a great extent
I think it was Fabian Nicieza that had a gorilla ask "could that butt be any more perfect?" about Dick's ass, though (also, I could be wrong). And Bruce Jones had Dick's then-lover refer to his bruises as "very hot". And then had Dick become a model. (I wish I was making the last two up so, so much.) So either Dick's another level of fetishization altogether, or we're more aware of Devin Grayson doing it because we all know she's a Nightwing fangirl. I know that's how/why I'm aware of it, at least.
