The complex reflexes of sexual intercourse and the differences in steps between men and women

Sexual activity – a complex reflex activity

The concept of sex life, as commonly understood, seems familiar to most people. However, many don't fully understand it, assuming it's simply sexual intercourse (commonly known as "having sex"). These are not the same thing. Sexual intercourse is merely one step in a sexual life. In reality, a sexual life encompasses much more.

So, what exactly does sexual activity include?

Sexual activity is an extremely complex reflexive process. Male sexual activity includes several steps: sexual desire, penile erection, intercourse, ejaculation, orgasm, and sexual arousal. While the intercourse itself differs from the male process, the entire process of female sexual development differs significantly. Female sexual activity can essentially be summarized in the following steps: sexual desire, vaginal gland secretion, passive intercourse, orgasm, sexual satisfaction, and sexual arousal.

These steps of sexual intercourse are artificially divided for ease of explanation. In reality, these steps are continuous, and some steps do not have clear boundaries. For men, after sexual stimulation, sexual desire arises quickly. Once sexual desire arises, the corpora cavernosa of the penis immediately become engorged with blood. The penis then immediately enlarges, hardens, and becomes erect. After erection, the desire for intercourse arises to obtain pleasure. Intercourse is the man's active action; after penile insertion into the vagina, if there is continuous friction, sexual desire usually reaches orgasm within a few minutes, reflexively inducing ejaculation. Maximum pleasure and sexual satisfaction are obtained at the same time as ejaculation. Afterwards, sexual desire immediately subsides, the penis softens, and the body feels fatigued and drowsy. Thus, sexual intercourse ends. If these steps are uninterrupted, they can all be completed within a few minutes. The development of female sexual desire is much slower than that of men. After sexual stimulation and arousal, women generally need a period of time, ranging from a few minutes to several tens of minutes, before they become sexually aroused. After sexual arousal, the clitoris, like the penis, becomes erect due to increased blood flow to the corpora cavernosa. The vaginal glands (mainly the vestibular glands) gradually secrete mucus, lubricating the vagina. Initially, there is no desire for intercourse; as sexual desire develops, pleasure gradually focuses on the genitals. At this point, the woman is willing to have penile penetration and desires male-initiated intercourse. Pleasure is obtained through the friction of the penis against the clitoris and vaginal walls. After several minutes to tens of minutes, sexual desire gradually reaches orgasm. However, sexual desire is not fully satisfied at this point; it takes some time for the desire to gradually decrease before the final satisfaction subsides. Female sexual intercourse generally lasts for tens of minutes, but experienced couples can significantly shorten the time.

Sexual activity is an extremely complex physiological activity involving all stages of sexual development. Furthermore, the processes of sexual development differ significantly between men and women. Therefore, to achieve a perfect and harmonious sex life, men must actively take steps to induce and stimulate female sexual desire. This includes pre-coital hugs and kisses, caressing the thighs and breasts, and post-coital caresses. Even engaging in sensual conversation before and after intercourse is considered part of sexual activity. Therefore, the meaning of sexual activity is not limited to intercourse; it includes all steps in the development of sexual desire and the behaviors undertaken to achieve sexual harmony. Some couples, primarily husbands, lack hygiene knowledge and understanding of the development of sexual desire, mistakenly believing that sexual activity is simply intercourse. Consequently, they often rush things, neglecting pre-coital preparation and post-coital caresses, resulting in deficiencies in their sex life and preventing women from achieving their due satisfaction. Some couples, lacking sexual knowledge and failing to accumulate experience, have, despite having children, never experienced the pleasure of sex, which is truly regrettable.
