The nipple is the small part in the middle of the breast that sticks out. With some girls they are very sensitive, while others feel nothing special when they are stimulated.
Size and shape varies greatly from girl to girl. The areola can be small as a euro or big as a beer mat. This is independent of the size of your breasts. You can have small breasts and big nipples or big breasts and small nipples.
Blonds normally have pink nipples, brunettes have brown ones and with dark skinned people they can be almost black. In most women they get darker after pregnancy.
The nipples can protrude and be clearly visible through clothing, they can be rather flat of be inverted.
A lot of guys love it when you stimulate their nipples during lovemaking. So ladies: don’t forget this sensitive spot if you want to give your lover a good time.

Some techniques to stimulate the nipples

When my boyfriend stimulated my nipples white fluid came out. Is this a sign of cancer?
I think I have a third nipple under my right one. It looks strange. Can I have it removed?
I’m ashamed because my nipples don’t stick out like those of others. They point inwards!
