I've heard a few chicks with big'uns complain and wish they were smaller (I even have a friend who had a breast reduction because hers were too big, she's too short and her back was giving her fits)...but I haven't known too many small-chested women who haven't wished for even slightly bigger because all the guys ogle bigger tits or suggest to smaller-chested women that they get boob jobs.

I definitely can dig the nipple-whiplash thing and that it's not quite so pleasant to deal with. That I don't envy...I just envy the ogling. :D
