Well it depends. If you have gotten your period. But if you are 10 dont worry much about it. If you are 11-15 by now you your breasts should be popping out. I wouldnt worry to much about them if you are 11-13 . But dont worry. As your breasts grow so will your nipples.
Normally they do not, but inverted nipples to occur rarely. At birth all nipples are inverted, this is because of the way glands develope as an embryo, but normall proliferation of the mesenchyme behind the nipple will push it out shortly after birth.
the same way if you arent fat the same way if you arent fat the same way if you arent fat
All humans, both male and female, have nipples. The only way a person will not have nipples is if they have been surgically removed. If someone should be born without nipples (either male or female) this is an abormality. Related link: http://en.wikipedia.org/wiki/Nipples
a dog produces milk throughout all her nipples. there is no way to tell unless you get a ultra sound
Sexual stimulation is one way, and another would be that she is cold.
The same way you make a guy's nipples hard.
no
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!

Well, your nipples swell when you get aroused or cold. But apart from that, there is no permanent way to increase the size of your nipples.
Yes, there are different types of nipples in men, just like there are in women. Some men may have protruding nipples while others may have inverted nipples. Nipple size, shape, and color can also vary among individuals.
maybe they are dead. maybe you need a new one. maybe they arent plugged in all the way
