The human sexual response cycle consists of four stages: excitement, plateau, climax and resolution. This model, first proposed by William H. Masters and Virginia E. Johnson in their 1966 book Human Sexual Response, remains a cornerstone of sex research today. Although this model provides a basic framework for sexual physiology, over time researchers have discovered significant differences between the sexes during the stages of sexual arousal.
The excitement phase is the first stage of the sexual response cycle, usually triggered by physical or psychological stimulation, such as kissing, kissing, etc. Key features of this stage include increased heart rate, breathing, and blood pressure. The survey found that about 82% of young women and 52% of young men would increase their sense of excitement when their sexual excitement was directly stimulated.
In both men and women, the arousal phase causes an increase in heart rate, breathing rate, and blood pressure.
In men, the onset of arousal is usually marked by an erection of the penis. The penis can reach an erection within a few seconds and may partially lose and regain an erection throughout the arousal phase. In addition, as arousal deepens, the scrotum contracts, pulling the testicles toward the perineum.
For women, the excitement phase may last from a few minutes to several hours. As blood flow increases, swelling of the clitoris, labia, and vagina becomes apparent. The vaginal lining will begin to secrete lubrication, and the breasts will increase slightly and the nipples will harden.
Women exhibit a variety of physiological changes during the arousal phase, including clitoral swelling and vaginal lubrication.
During the plateau stage, the heart rates and blood pressure of both parties rise further, and they show intense sexual pleasure. The physiological responses during this phase are similar between the sexes, but for men this phase is usually accompanied by the secretion of semen, while women experience vaginal tightening and further lubrication.
Women experience contractions of the uterus and vagina during orgasm, and the sensations vary from woman to woman.
After the climax, the resolution phase begins, during which muscles relax, blood pressure drops, and the body gradually returns to a non-aroused state. For men, this phase is usually accompanied by a brief period of inability to re-enter arousal, the so-called re-responsiveness period, while women can quickly return to a state of arousal and may reach orgasm again.
Similarities and differences between the sexesDue to the existence of the re-orgasm period, it is usually difficult for men to have repeated orgasms in a short period of time, while women have a higher probability of achieving multiple orgasms.
Although Masters and Johnson's research showed that the sexual response process is somewhat similar in both sexes, many studies have pointed out that there are still significant differences between male and female responses. For example, men usually react relatively quickly to stimulation, while women's excitement may be more complex and more influenced by emotional factors.
Today, scholars have proposed different sexual response models. These studies are not limited to the physiological level, but also introduce psychological and emotional factors in order to more comprehensively understand the differences in sexual performance between the two sexes.
The introduction of these models not only enhances our understanding of sexual response, but also promotes the recognition and treatment of sexual dysfunction.
Looking back at various studies on the human sexual response cycle, the differences between genders are not only in physiological manifestations, but also involve multiple levels such as culture, emotion and cognition. Faced with such complexity, we can't help but wonder: In the pursuit of a more satisfying sexual relationship, what impact do gender differences have on the compatibility of both parties?
