You know... I think I'd look. But on some level, they've been desexualized for me. I work around children and babies and breastfeeding women. There are naked breasts everywhere at work, usually with a child attached to them. I guess I do see them in public and have developed a little switch in my head that I can flip from "Oh, those are NICE!" to "Boob = Happy baby."
Of course, I'm proud of mine. I know the effect they have on people who don't have or use that switch.
