No they do not, nipples are not needed. Nipples are a feature of mammals, which suckle their young. Cockroaches are insects and do not suckle their young so they do not have nipples.
The nipples get larger so as to better suckle the baby.
so they can suck on them
Because they are, Simple!
nipples
they can rub their nipples
its because when you are a zygote then you can either be a boy or a girl so the nipples develop anyway
It all depends on the way your nipples were made!some are squished in and some are pointy!if your nipples are pointy it doesn't matter if they're squished in that's fine too!
No. A male cat's nipples do not produce milk so never "dry up" in the first place. A cat's nipples are part of the body.
nipples vary in size, so yes they're normal.
Every mammal has nipples. It is through the nipples that newborn mammals access the milk their mothers produce for them (the perfect food for a newborn mammal).
Well, just so you know, NOTHING is wrong with your nipples. if they are itchy, then it means your breasts and nipples are developing. some people have itchy nipples and some others dont. its nothing to be worried about. im a doctor. i KNOW what im talkin about.
