The red protrusion on the tip of the breast Erection may occur due to sexual arousal
Generally, the nipple protrudes from the areola, but it may be depressed in the areola, and the depressed nipple is called an inverted nipple. There are also pseudo-inverted nipples in which the nipple is exposed by erection, and true inverted nipples in which the nipple is buried even after erection. In the latter case, medical nipple piercing etc. are used. Sometimes used to expose nipples
The number of nipples is generally one for each boobs, for a total of two.
Also, the glans penis of the clitoris, which is also called the girl's penis, is sometimes called the devil's nipple, and if this is included, there will be three nipples in the case of women. This devil's nipple exists only in women, and in a sense it can be said to be a more feminine nipple than the upper nipple. This third nipple may also be depressed in the clitoral hood, but such a clitoris is called a phimosis clitoris. The devil's nipple, the clitoris, is easier to erection than the nipple, so if the nipple is erected, most of the time, both the third and the nipple are erected, but all three nipples are erected. Sometimes it's an erection both above and below
Although uncommon, women with double breasts will have more than three nipples.
