In sexual life, breasts are constantly changing. Let's take a look at their changes. Women in movies, television, pictorials, and literary works always have plump breasts. Breasts are important sexual organs for women, and they also play an important role in sexual activity, but people often overlook this. The distribution of nerves and the number of nerve endings in the breast are abundant, and the relationship between the breast and other sexual organs is very close.
The first evidence of enhanced breast response to sexual tension during the excitement period of the sexual response cycle is the erection response of the nipple, which is the result of involuntary contraction of the abundant smooth muscle fibers in the nipple after sexual stimulation. The reactions of the two nipples often do not occur synchronously, with one possibly achieving complete erection and swelling, while the other exhibits a lag phenomenon. The inverted nipples may protrude from their resting state, as if in a semi erect position. If this inverted nipple is difficult to recover, then there is no indication of nipple response.
The sufficient erection response of female breasts can increase the length of the nipple compared to before stimulation, generally increasing by 0.5-1.0 centimeters. The response can also increase the diameter of the nipple base by 0.25-0.5 centimeters. Usually, those with large and protruding nipples tend to have a smaller tendency to swell and erect compared to those with normal size. It is difficult to respond strongly to sexual stimulation even when the nipples are very small, but it is not common for nipples to be very small.
The second physiological change during the excitation period of women's breasts is the demarcation and expansion of the breast vein tree pattern. If the breast has sufficient volume, there will be congestion of the superficial veins 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 towards the center, it usually does not reach the areola area.
In the approaching plateau period, the actual volume of the breast will significantly increase, which is the result of deep venous congestion reaction in the breast. Women in a state of sexual response are more likely to observe congestion in the lower part of the suspended breast during an erection reaction. If the woman is in a supine position, the overall increase in breast volume will be more significant. In the late stage of excitement, obvious areola congestion can be observed.
The degree of expression and occurrence time of excitatory reactions vary greatly, often depending on the individual and time. During the plateau period, the areola adjacent to the erect nipple can also become enlarged, often creating an illusion that the erect nipple has partially subsided. It is not until the swelling of the areola subsides during the regression period that people can see the nipples that have remained erect and have subsided later.
Before women experience the final orgasmic impulse, the size of breasts in women who have not breastfed can increase by 1/5-1/4 compared to usual, and breast size in women who have breastfed usually does not show a significant increase in breast volume. This anatomical difference may be due to an increase in venous shunting during milk production in breast milk. Babies sucking can increase venous shunting and tend to slow down the congestion response of deep blood vessels during sexual tension.
It is evident that the increase in breast size under the influence of sexual tension is not only related to the physiological response of vascular congestion, but also to the degree of enrichment of the fibrous tissue components that support the breast lobules. In the early stages of lactation, excessive breast expansion is common, which can damage the effectiveness of these supporting fibrous tissues. Therefore, it can be understood that the breasts of lactating women are difficult to respond to sexual stimulation as clearly as they should.
After entering a plateau of sexual tension, pink patches often appear in the front, side, and even below the breasts of women. In fact, this patchy mound rash first appears in the epigastrium, and then spreads to the breast surface. This vascular congestion reaction on the skin surface is called sexual erythema.
There are no specific reactions in the breasts during female orgasm. The nipple erection and areola swelling have been determined, and the venous tree protrusions appear very prominent. Breasts that have not been breastfed have significantly expanded compared to the baseline before stimulation, and sexual redness is very clear. Breasts may even experience shaking.
The arrival of the female breast regression period is signaled by the rapid disappearance of sexual redness and synchronous disappearance of areola swelling. But nipple erection subsides slowly, and when the swelling of the areola subsides, the nipple erection becomes prominent again, giving the impression that they have experienced secondary erection reactions caused by the influence of new or existing stimuli. People call this false appearance "false erection".
Kind reminder: The above is an introduction to the physiological reactions of breasts during sexual activity, hoping to be helpful to everyone. This is only a reference, and I wish you good health.
