How about I turn the question around to the guys who say size dun matter. Do boob size matter ? You could argue that the service matters more than boobs, but man, all things equal, big boobs = more gaga and more fun !

And I could say the same about dicks too. Though what you do with your dicks is very impt, all things being equal ( ie, 2 equally skilled persons ), the bigger/thicker dick is probably more arousing and exciting to the girl, but only up to a point when it becomes too big and scary, of coz.
