While the nipple has alot of nerve endings that does not mean that it is the most sensitive area. Personally I find my nipples to have the LEAST sensitivity.
5'5" ..and im either a 34B, 36B or 34C, it all depends. but one of my breasts is larger than the other by about a half a cup but they are adorable and perky, with pink nipples. i love them
5'8" and typically a 32B - 34B (ideally I'd be a 33B) but I'm on the way up at the moment, my wee boobies are growing. I'm spilling out so I'll have to get the tape measure out and dig out a bra deep from my drawers that's a c-cup (there's a couple in there somewhere) to see which I'm more comfortable in. This is exciting news for me, especially since I'm in my mid-twenties! I like my boobies these days. Perhaps not a little while ago, but they're actually pretty boobies. The few select people that have seen them have also loved them
