What is sex
- Sex is the source of human life and an integral part of life. Sexuality is a part of our everyday thoughts and emotions, whether we are actively involved or not. It is rooted in our dreams, desires, fears, and frustrations.
- For some people, sex controls them and they spend most of their time and energy on it; for others, by chance, or by personal choice, sex is in their lives with no significant effect. For most of us, however, sexual attraction depends on our inner needs and changes in external circumstances, sometimes stronger and sometimes weaker. Sex manifests differently at every level of life.
- Biologically speaking, the primary function of sex is reproduction—to bear children. Biology provides a mechanistic picture of sexual function and behavior, with elements ranging from genes to genitalia. Sexual function is regulated by nerves and hormones and is maintained by blood circulation, muscles, and other systems in the body.
- At a psychological level, sex consists of a series of behaviors and relationships aimed at sexual pleasure, affection, and other needs.
- On a social level, sex pervades all aspects of life, it makes your culture unique and adds to its art, history, law, and value.
- Also, sex plays a lot of indirect roles in your life. It's a big part of your gender identity (masculine masculinity, feminine femininity) and a big part of what people expect from your social role. Sex can convey dominance and hostility, it affects your self-esteem and social status, and it shapes your life in several other ways, from infancy to old age.
The knowledge about sex
- When many people have an erection, the penis will bend a little, and the degree varies from person to person, some will bend up and down, and some will be left or right.
- Sperm production takes about 90 to 116 days and can survive in the vagina or cervix for 72 hours.
- Most of the penis is made of the corpus cavernosum, which is covered with a layer of the epidermis. When sexually excited, the corpus cavernosum will become congested, making the penis hard, longer, and thicker for sexual intercourse. "Erection".
- Don't put rubber bands or bands on the penis to prolong the erection time or prevent him from ejaculating. This is very likely to cause blood to clot and cause the tissue of the penis to necrosis.
- If the penis is hit violently, it will break and it will make a loud noise. In this case, it must be sent to the hospital for treatment as soon as possible.
- When a woman's vagina is not lubricated enough but forcibly enters, and the action is too intense, it will not only make the woman feel pain but may also cause you to break the foreskin. Although most will heal on their own, severe wounds may require stitches.
- Stop the sexual activity immediately when the testicles become inflamed, white or yellow discharge from the penis, pain, and discomfort when urinating, or discharge from the anus when irritated, because all of the above symptoms can indicate that he may have STDs, you should see a doctor immediately.
What are the dangers of excessive sex
- For both men and women, it will cause greater physical consumption. Over time, it will inevitably lead to a decline in physical and mental state, thinking ability, memory, and analytical ability.
- Due to the continuous and repeated occurrence of sexual impulses, both men and women will increase the burden on the sexual control nerve center and sexual organs, and regular fatigue will cause sexual function failure instead, resulting in "pre-aging" of sexual function.
- Men often have sex multiple times, which will prolong the ejaculation time. Because the second time ejaculation appears longer than the first time. This lays down the hidden dangers of inducing impotence, non-ejaculation, delayed ejaculation, and no pleasure in sexual life.
- Men have a refractory period after sex, that is, they no longer respond to sexual stimulation for some time after sex. Repeated sex life will prolong its refractory period, and it is easy to cause sexual function decline.
- Men often have sex many times. Due to the repeated and persistent congestion of the sexual organs, will induce prostatitis, seminal vesiculitis, and other diseases, resulting in perineal discomfort, back pain, and blood sperm. Women often have sex many times, and their sexual organs are always in a congested state, which will induce pelvic congestion and heaviness in the lower body.
- Regardless of men and women, the degree of sexual satisfaction is worse than the previous one when they have sex multiple times, so it is easy to cause psychological impact, thinking that there is a problem with their sexual ability, which may eventually lead to psychogenic sexual dysfunction.
What is the role of sex
- Breed offspring
- Soothing treatment
Moskowitz, an expert at the New York University Medical Center, affirmed the efficacy of "sex". Regardless of your symptoms, perfect sex can have a healthy effect on you, he says. Emotions and physical health are closely related. Negative emotions such as anger, worry, guilt, and sadness can trigger a stress response in the body, have adverse physiological effects, and ultimately impair the function of the immune system. Happy sex life can generate positive emotions such as interest and excitement and can eliminate tension. According to Moore, the nervous system releases endorphins—a natural pain reliever—during sex, which relaxes body tissues.
For the therapeutic effect of sexual life, the following aspects can be cited:
- About sex and heart: Experts believe that insatiable sexual desire is one of the predisposing factors for heart disease. In a study of 100 women with heart disease undergoing treatment, it was found that 65 of them had unsatisfied libido before hospitalization. In another study of 131 men with heart disease, two-thirds had severe sex problems before the onset.
- About the immune system: In a study of breast cancer patients, experts found that sexually satisfied women had more T cells (white blood cells that play a major role in immune function) in their blood, and they lived longer.
- Regarding premenstrual syndrome: 5-7 days before menstruation, blood flow to the pelvis increases, causing swelling and abdominal pain. During orgasm, the emotions are extremely excited, and muscle contractions force blood to flow out of the pelvic area quickly, making the pelvic tissue relaxed.
- Treatment of pain: Orgasm is a natural pain reliever. An excited orgasm can significantly increase the pain threshold. When the so-called live endorphins reach the receptors throughout the body during orgasm, they have a morphine-like effect, so they can relieve many kinds of pain. Sex is also a sedative, it soothes the body and eliminates insomnia. The better your sex life, the easier it is to fall asleep.
- For mental health: a happy sex life can produce a good mental state. A San Francisco research institute analyzed the sex lives of 37,500 adults and found that those who had a good sex life had fewer worries, violent beliefs, and hostility. This happy feeling extends to each other between spouses and into the couple's relationship. Gentle sex can help people show their best peace of mind.

- Helps to eliminate insomnia. Everyone longs for deep and sweet sleep, but insomnia caused by various reasons often troubles everyone. Women, in particular, are more prone to insomnia. After experiencing a harmonious sex life, the nervous and excited body begins to relax, the muscles are also stretched in the tiredness after being satisfied, and drowsiness strikes naturally, which helps to eliminate insomnia. And the happier your sex life is, the easier it is to fall asleep afterward.
