How to protect breasts during sex?

　　Therefore, in movies, TV, pictorials, and literary works, female Always had plump breasts. Breasts are important sexual organs for women, and they also play an important role in sexual activities, but people often ignore this. breast nerve The distribution and number of nerve endings are very rich, and the relationship between breasts and other sexual organs is very close.

　　During the excitement phase of the sexual response cycle, the first evidence of increased breast response to sexual tension is the erectile response of the nipple, which is the result of the involuntary contraction of the rich smooth muscle fibers in the nipple after sexual stimulation.

　　The reactions of the two nipples often do not occur simultaneously, and one may have reached full erection and swelling while the other lags behind. Inverted nipples may bulge out from their quiescent state, as if in a semi-erect position. If this inversion is difficult to recover, there will be no nipple reaction indications.

　　A sufficient erectile response can make the nipple length increase compared to before being stimulated, generally by 0. 5-1. 0 cm, the reaction can also increase the diameter of the nipple base by 0 cm. 25-0. 5 cm.

　　Usually, those with large nipples that protrude forward tend to have smaller swelling and erection tendencies than those with normal-sized nipples. It is difficult for nipples to respond strongly to sexual stimulation if they are particularly small, but it is rare for nipples to be particularly small.

　　A second physiological change during the excitement phase is increased delimitation and expansion of the breast venous tree pattern. If the breast is of sufficient volume, underlying superficial venous congestion will occur, but probably will not become more definite until later in excitement. Larger breasts often exhibit a pronounced expansion of the venous tree pattern. The hyperemia of the breast venous tree usually does not reach the areola area as it expands toward the center.

　　As the plateau approaches, the actual volume of the breast increases significantly, which is the result of a hyperemic response to the deep veins of the breast. When a woman in a sexually responsive state has an erectile response, the congestion at the lower part of the hanging breasts is easier to observe. If the woman is in the supine position, the overall increase in breast volume will be more obvious. Obvious areolar congestion can be seen in the late stages of excitement.

　　The degree of expression and time of occurrence of the excitement phase reaction vary greatly and often vary from person to person and from time to time. During the plateau phase, the areola adjacent to the erect nipple will also swell, often giving people the illusion that the erect nipple has partially subsided. It is not until the areolar swelling subsides during the resolution period that people can again see the nipple that has remained erect after the later resolution.

　　Before a woman experiences the final urge to climax, the size of the breasts of women who have not breastfed can increase by 1/5-1/4 than usual. The breasts of women who have breastfed usually do not show a significant increase in breast volume. This difference in anatomical presentation may be due to increased venous shunting during milk production in the fed breast.

　　baby Sucking increases venous shunting and tends to slow down the hyperemic response of deep blood vessels during sexual tension. Obviously, the increase in breast size under the influence of sexual tension is not only related to the physiological response of blood vessel congestion, but also related to the fullness of the fibrous tissue components that make up the supporting breast lobules.

　　Overexpansion of the breasts, which is common in early lactation, impairs the effectiveness of these supporting fibrous tissues. Therefore, it is understandable that the female breasts after breastfeeding are difficult to respond to sexual stimulation as they should.
