I'm 12, and my boobs really, REALLY hurt. Not just like, all the time, but if any pressure at all is applied (politest way I could think of putting it), they hurt a LOT. I wear a padded bra, but even still, if I'm in a crowd or something and someone bashes into my chest, I could almost scream, it hurts so much. I've seen another discussion about this, but none of the replies really answered the question WHY well enough for me, so I'm going to ask it again.
Why?
