Although I confess I've never seen a pair I didn't like, I'm curious about whether the size of the nipple or areola make a difference in a woman's ability to handle punches to her breasts. My wife's areolae are less than an inch and a half in diameter, but she has huge nipples which are the size of my little finger and stick out over half an inch when she is aroused. She is very self-conscious of her "headlights" and almost never goes without a bra. She claims big nipples are a disadvantage in a fight because it feels like they are being knocked off her breast when she is punched, and they are targets for her opponent's fingernails. However, I've noticed that her areolae have gotten very red, swollen and puffy during and after a fight, while the rest of her breast remains normal except for some redness. I wonder if the bigger the areolae the more swelling and perhaps pain would occur.
Anyone have an opinion as to which breast type constitutes a "glass jaw" for women? I haven't brought up size, so feel free to include that discriminator as well.
