Lovemaking is an essential aspect of any healthy relationship yet some couples are not aware of how the bodies change during the intercourse. While making love, a woman’s body goes through four different stages that trace the evolution of her sexual desire. Each stage has its own characteristics of specific physical responses and the woman’s breasts play a vital role in making the experience a pleasing one.
1. The excitement phase: This is the first stage of having sex where the mutual stimulation prepares the vagina. The first sign of sexual arousal is experiencing a vaginal lubrication that typically happens within 10 to 30 seconds of the stimulation. As the excitement builds up, the amount of fluid increases and the nipples also become erect. This happens mainly due to the contractions in small muscle fibres that respond to the sexual arousal.
2. The plateau phase: This is when the sexual stimulation is even more intense and the orgasm is just about to occur. The opening of the vagina narrows by about 30 percent for gripping the male genitals. Sometimes the colour of the inner vaginal lips also changes from pink to bright red. And the whole body reacts to the sexual arousal, and about 50- 75 percent of women across the world experience red spots resembling measles in and around the breasts, face, neck and buttocks. This is called as sex flush.
3. Orgasm: This is the juncture when the female body reaches the throes of the sexual pleasure and is immediately followed by relaxation. The breasts can swell by up to 25 percent at this stage. This makes the breasts ultra-sensitive and much larger than their original size. The nipple stimulation leads to the activation of same areas of the brain like the vaginal, cervical and clitoral stimulation. And the nipples turn from a pale to a deeper hue with the increase in the blood flow during the arousal.
4. Resolution phase: At this stage, the rate of blood pressure as well as heart rate fall as the woman calms down at this stage. But if sexual stimulation continues, then the resolution phase would span a very short time and the woman is likely to go back to the first three stages for further orgasms that lead to temporary enlargement of breasts.
Thus there is nothing to be worried about if you experience swelling of breasts when you are sexually aroused. However, if you feel that your breasts have become tender or causing any sort of abnormalities, then you must speak with a sexologist without further delay.
