He,he,he..Sorry, do not mean to laugh, but when I saw your post I thought, "Wow! It's NOT just me!"
I am considerably larger on my left side than my right (I am right handed and therefore was more comfortable feeding this way).
I swear I'm at least a 1/2 cup size larger on my lfeft side. My dh does not think I need to see a specialist to correct this problem, but it does make me a bit self conscious - especially when I jump in the shower, or take a bath, or stand in front of him naked...Yikes!!! Glad we are not alone~!
