Why do nipples become erect during sexual arousal? Are nipples a sensitive area for women

Soldiers often say that knowing oneself and the enemy is invincible in all battles. And only by understanding each other can we better cooperate with each other. LELO once said that mutual communication and understanding can make sex more perfect. So, do you know some physiological reactions of women during sexual life? Only by understanding their sexual reactions can we better meet their needs and make sex more perfect.

The first evidence of enhanced breast response to sexual tension during the sexual stimulation cycle is the erection response of the nipple, which is the result of the abundant smooth muscle fibers in the nipple contracting involuntarily after sexual stimulation. The reactions of the two nipples are often not synchronized, with one possibly having a complete erection and swelling, and the other possibly lagging behind. The nipples may protrude from their resting state, as if in a semi erect state. If it is difficult to recover, there is no indication of nipple response.

Adequate erection response will increase the length of the nipple, typically increasing by 0.5 to 1.0 centimeters, and also increasing the diameter of the nipple base by 25 to 0.5 centimeters. People with large and protruding nipples often have smaller swelling and an erection tendency than those with normal size. The nipples are difficult to respond strongly to sexual stimulation, but they are very small.

The second physiological change during the excitation period is the definition and expansion of the breast vein tree pattern. If the breast has sufficient volume, there will be superficial venous congestion below, but it is likely to become clearer in the later stages of excitation. Larger breasts typically exhibit significant vein tree pattern dilation. When the congestion of the breast vein tree expands to the center, it usually does not reach the areola area.

Near the platform, the actual volume of the breast will significantly increase, which is a result of the deep vein congestion reaction of the breast. When an erection reaction occurs, congestion in the lower part of the suspended breast is more easily observed. If a woman lies on her back, the overall increase in breast volume will be more significant. Late sexual arousal shows obvious areola congestion.

The degree and timing of breast reactions during sexual arousal vary greatly and often vary from person to person. During the platform period, the areola near the erect nipple will also swell, often giving the illusion of partial disappearance of the erect nipple. Until the swelling of the areola subsides during the regression period, people can only see that the nipple that subsides later still maintains an erection.
