Either you have deformed hands, or you're so used to holding the controller in a way that wasn't intended because you've become so compensating for stretching for the analog stick that you don't even realize you're holding it awkwardly anymore.
Same answer as SvennoJ that gets the ergonomics backwards. Your symmetrical hands want the Analog stick in the default position and don't care about the aesthetics or glibness. What you are saying is that you'd prefer to stretch your finger constantly for an analog stick based on a completely unimportant aesthetic factor.
Haha sure. But now you mention it, I never found the original PS controller very nice to use.
Dunno what's going on with your hands, but my thumbs are naturally away from my index fingers. As I said they sit much closer to the analog sticks than where the D-pad is. I'm not even stretching, heck the analog stick actually sits more to the bottom of my nail.
But good to know my hands are 'wrong' and kind of Sony to make a controller to fit my 'wrong' hands :)
