During sexual stimulation, such as touching, caressing, kissing, etc., nipple erection, venous congestion on the surface of breast, breast fullness and enlargement, etc. These changes gradually returned to normal after orgasm.
Extended data:
Breast is mainly composed of glands, ducts, adipose tissue and fibrous tissue.
The longitudinal section of the breast is like an upside-down tree. The "root" is the nipple, while the "crown" is the breast leaves with many branches arranged radially. The subcutaneous tissue of the breast is adipose tissue.
The amount of adipose tissue determines the size of the breast. Fibrous septa from adipose tissue divide the breast into 15 to 20 breast lobes. Each breast lobe has a milk duct. The feeding duct forms an enlarged sinus of the feeding duct near the nipple, and the end becomes thinner and opens at the nipple.
There are many suspensory ligaments in breast skin and deep thoracic fascia, which are actually connective tissues. Its function is to fix and support.
