Why do breasts become hard?

Everyone knows that a man's penis will have an erection when stimulated and will become very hard. In fact, not only men can get hard, but women can get hard too, but it’s not the genitals, but the nipples. Many people say they don't know much about it, but that's okay. Who has nothing better to do than to study these things? In the final analysis, what exactly is the reason why women's breasts become hard?

Breasts are an important sign of female sexual maturity and one of the most important sexual sensitive areas of women. They also play an important role in sexual life, but people often overlook this point. During the excitement phase of the sexual response cycle, the breasts respond to sexual stimulation because the rich smooth muscle fibers in the nipple contract involuntarily after sexual stimulation.

When adequately stimulated, the actual volume of the breasts will increase significantly, which is the result of the congestion reaction of the deep breast veins. When a woman is in a state of sexual response, the congestion in the lower part of the pendulous breast is more easily observed when the response occurs. If the woman takes the supine position, the overall increase in breast volume will be more obvious. In the late stage of excitement, obvious areola congestion can be seen.

Before a woman experiences the final urge, the breast size of a non-breastfeeding woman can increase by 1/5 to 1/4 compared to usual. The breasts of a breastfeeding woman will also change, but no obvious increase in volume can be seen. This difference may be due to increased venous shunting in the fed breast during milk production. The infant's sucking increases venous shunting and tends to slow the deep vascular congestion response to sexual tension.

The increase in breast size under the influence of sexual tension is related not only to the physiological response of vascular congestion, but also to the degree of fullness of the fibrous tissue components that make up the breast lobules and play a supporting role. Overexpansion of the breasts is common in early lactation, which can impair the effectiveness of these supporting fibers. Therefore, it is understandable that it is difficult for a woman's breasts to respond as clearly to sexual stimulation after breastfeeding.
