I dunno, how do we actually define "large" breasts? My partner is under the impression that for cup sizes:
AA = tiny
A = small
B = average
C = big
D and beyond = huge
For him, this system is pretty hard and fixed. I have issues with this system, because as any lingeriephile would know, the cup size is relative to the band size -- so my 30C breasts don't appear to be "big" because the cups are the same size as the cups in a 34A...only the band is smaller. I consider myself to be a member of the itty bitty titty committee as well (and I'm happy with it)! Mine are rather spread out across my chest, and I only need a C cup because they spill over as soon as they're contained.
Anyway, IMHO, boobs are boobs are boobs, and whether they're small or large, they're all beautiful. The female form is wonderful in all its many shapes and sizes.
