What IS female arousal? With men, it is pretty straightforward to determine whether a man is aroused or not. Is the penis erect or not? Of course, there are nuances to this but, overall, that’s the litmus test for men. What physiological signs are present when a woman is sexually aroused?
When sexually aroused (usually a combination of psychological and physical stimulation), women’s breasts usually become enlarged and the nipples become erect. Of course, there are various reasons for enlarged breasts and erect nipples, but they are usually present to some degree when a woman is aroused. The enlargement of the breasts is usually slight enough that it is rarely noticed. The veins in the breasts also become more visible as the breasts swell. Additionally, the skin may flush during arousal especially on the chest and neck. This is most visible in fair-skinned individuals. Approximately 50-75% of women experience flush during arousal, while only about 25% of men experience flush.
During sexual arousal, a woman’s vagina and reproductive organs undergo several changes. The vaginal lining moistens with lubricating fluid within 10 to 30 seconds of the beginning of arousal. This fluid is believed to be the “sweating” of the vaginal walls. The sweating resulted from the increased blood supply and the engorgement of vaginal tissues. Also the vaginal walls lengthen and distend, which pulls the cervix and the uterus slowly back and up into the false pelvis (the part of the pelvis above the hip joint). The engorgement of the vagina is a type of vasocongestion, a phenomenon also seen in menstruation, REM sleep, allergic reaction, and deeply emotional responses.
The glans in the head clitoris also become swollen and erect like a penis. (The clitoris, after all, is homologous to the penis–see this illustration for a better idea of how much like a penis a clitoris is, or really vice versa.) This reaction to arousal varies in degree between women. The labia majora swell as do the labia minora, though to a lesser degree.
Women’s blood pressure, breathing, and heart rate increase considerably during sexual arousal. This happens in order to accommodate the increased blood supply to various parts of the body with sufficient oxygen. Muscles throughout the body also become tense because of this. These and the above signs of arousal occur during the first two stages of the human sexual response as outlined by Masters and Johnson: excitement and plateau.
There are various other individual idiosyncratic responses that can occur during sexual arousal. For instance, some women report unprovoked sneezing, increased ticklishness, and swollen lips. So the next time you lay eyes on the one that makes your heart jump remember what’s going on with your body. Comments or questions? You know where to leave them. Thanks!
