As long as they aren't huge, deflated, or deformed, they all look nice to me. Small (not tiny) to medium and puffy are best though.
You know what men prefer? Tits that they can touch, lick suck etc etc they really don't care as long as it tits on a woman
I think they should be befitting of the boobs... it depends on the person's heritage, and how tan they are. I associate pink nipples with lighter skin, really.
that like eating crackers in bed. Any day you get to play with boobies, is a good day. Who cares what color, pink, white, brown, black.
Um, if you're 5'9 and weigh 101 lbs, you have an BMI of approximately 14.1, which means you're WAAAAY underweight, and probably dying. Average BMI for a woman is 18.5 to 22. Go see a doctor, please. Unless you're a troll, in which case, go away.
My girlfriend has puffy nipples, and they are amazing. Always been partial to them. Pretty much all nipple types are great though.
