Look it's science
No two nipples are the same, but apparently they can be divided into clinical categories. There are eight different types, according to Dr. Tsippora Shainhouse, M.D., a board-certified paediatrician and dermatologist from Beverly Hills. All of them are normal, and it’s not uncommon for a woman to have a mixture of a few.
Flat
The entire nipple is flat and blends into the areola. The nipple may protrude with stimulation or temperature change.
Protruding
The nipples are raised a few millimetres above the areola. While the nipple naturally appears more erect than others, it becomes more pronounced when stimulated.
Puffy
The areola and nipple looks like a raised mound on top of the breast. Nipples often retract inwards, but can harden or become more defined with stimulation.
Bumpy
Most people have called Montgomery glands, the small bumps on nipples, but they’re more protruding on some.
Supernumerary
Inverted
Literally when the nipples retract inwards. This is completely normal, but if you notice a change in your nipple shape contact your GP.
Unilateral Inverted
Hairy
Everyone has hair follicles on the nipple area, however some grow more than others. They’re completely normal, and it’s fine to pluck them if you want to.
