sex life and health
"Wu Zi" said: "Food, sex, and sex."This sentence shows that sex and food are as natural as human beings.Modern medical research proves that loving husband and wife, harmonious and moderate sex life can make people healthy and live a long life.The reason is that a harmonious and moderate sex life can adjust the tension of people's work and study, relax the tense body, and obtain great pleasure from sex life.When a person is in a happy mood, the body can secrete some substances that are beneficial to human health, such as hormones, enzymes, and acetylcholine, which can accelerate blood flow, adjust the excitement of nerve cells to the best state, and promote the metabolism of the whole body, thereby delaying aging and prolonging life. .

A harmonious and moderate sex life can improve the physical and mental health of both husband and wife.On the contrary, in the case of equal material life, if there is no sex life, it will make people emotionally unstable, spiritually empty, and restless.Sexual medicine experts have found that the average life expectancy of widowed, widowed, lonely, lonely, marital breakups, enemies, or different dreams is significantly shorter than that of loving couples by more than 10 years.A harmonious and moderate sex life is more important to the elderly.The greatest distress and inferiority complex of the elderly is the feeling that youth is gone forever. With the decline of sexual life ability, physical strength and the functions of various organs in the whole body obviously decline, and they feel that vitality is weakened, and their distress and inferiority complex become more and more serious.Because people are busy studying, working, raising children and caring for the elderly in their youth and middle age.The spiritual life is tense and orderly, the sexual life is harmonious and happy, and everything behaves logically.In old age, social work and responsibilities are decreasing day by day, children have grown up, started a family, set up a business, and set up a separate house. The trivial affairs of the family are significantly reduced, and they often appear to be doing nothing.At this time, although the sex life cannot be as enthusiastic, happy and fulfilling as the young and middle-aged people, but they can feel the comfort of the other party more deeply, exchange feelings more, and have a feeling of being dependent on each other, thereby enhancing the self-confidence and confidence of the elderly in life. vitality.

However, indulgent, unscientific sex life is detrimental to health.For example, the three palaces and six courtyards of the emperors in the past dynasties, the concubines and concubines are like clouds, most of them are indulgent, and the average life expectancy with a life record is only 39 years old, while the Emperor Qianlong of the Qing Dynasty learned the lesson of the short life of the emperor and proposed the health preservation of "drinking easily and not being obsessed with sex" As a result, he lived to the age of 88.Modern medical research has proved that excessive sex life and frequent infertility can reduce the function of the anterior pituitary gland, thereby accelerating aging.Clinical practice has also proved that excessive sex life can lead to weak waist and knees, dizziness, tinnitus, forgetfulness, fatigue, dull complexion, abdominal pain, lethargy, disease, and even sudden death.

Numerous facts have proved that a harmonious and moderate sex life can make people energetic, feel comfortable, have quick thinking, and sublimate the relationship between husband and wife, which is of great benefit to work, study and life; lack of sex life will make people feel dull and boring life, lack of energy, Not good for health; and excessive sex life can lead to disease, endanger physical and mental health, and even shorten lifespan.

1.Harmonious sex life

Sexual harmony refers to the tacit cooperation and coordination between men and women to complete sexual intercourse together, so that both parties can obtain sexual pleasure and joy.In real life, not every couple's sex life can reach the realm of sexual harmony.Often due to disharmonious sex life leads to emotional incompatibility, extramarital sex, family breakdown, and even tragedies.Therefore, a harmonious sex life is an important factor in a happy and happy relationship between husband and wife.How to make sex life harmonious, complete and happy?

(1) The standard of sexual harmony is sexual satisfaction, which is the satisfaction of psychological and physical sexual desires at the same time.Both husband and wife feel a kind of unique euphoria, happiness, and the whole body is relaxed and comfortable.Frank Beech, a world-renowned sexologist, pointed out: "There is nothing else in the world that can closely combine people's physical desires and psychological consciousness like sex." A harmonious sex life can promote the relationship between husband and wife and stabilize the family. Harmonious sex life can regulate endocrine and reduce diseases, such as many girls have general fatigue, breast tenderness, irritability, headache, depression, insomnia, back pain, abdominal pain, edema and other discomforts before menstruation , often referred to as "premenstrual syndrome."After marriage, these symptoms can gradually disappear through a harmonious sex life.Another example: monks who have never been married have a significantly higher incidence of prostate cancer than married men. This is because the prostate is a gland that secretes semen and cannot play its physiological role for a long time, resulting in disuse embolism and malignant transformation.Harmonious sex life can stimulate the nerves, promote the regulation of nerves and body fluids, promote the secretion of adrenal glands and gonads, and delay the aging of these organs.

In addition, a harmonious sexual life does not mean blind pursuit of orgasm. According to relevant surveys, not all men and women can experience orgasm during sexual life. Some literary and artistic works exaggerate orgasm, which can easily mislead some people to blindly pursue orgasm, and even Affect the normal sexual life of husband and wife.

(2) Harmonious sex life requires a good spiritual mood as a prerequisite. Before sex life, both husband and wife must have desires and interests, and fall in love with each other.It is often that one party expresses the desire to make love to the other party through subtle and tactful language, or even certain actions or hints.It could also be a straightforward "I want."no matter how you express it.As long as it can make the other party understand, understand or tacitly, it is enough, and it must not be forced.Because sex is built on the basis of love, and only when the two are happy can a harmonious sex life be achieved.If one party does not respect the wishes of the other party and makes the other party reluctantly obey, it is impossible to achieve sexual harmony.Sex life is a direct reflection of the intimate, dear and sincere feelings that a man and a woman have for each other. If this is violated, it will violate the basic principles of human nature, and it is impossible to have a harmonious sex life.

When one party sends a sexual desire signal, and the other party fails to consent due to physical discomfort or other reasons, the rejecting party should give warm and tender comfort, such as "I'm sorry dear, I'm too tired today".The rejected party should wait patiently, or be more concerned and take care of the other party, so that the other party feels the call of love, thereby arousing sexual excitement.In fact, both husband and wife should not hide their feelings, and don't be afraid of being rejected by the other party and suppress their desire for sex.

When the sexual desire is acquiesced by the other party, the husband and wife should perform the "prelude" before making love, and arouse the psychological and physical sexual excitement of both parties through intimate actions such as love talk, play, flirt, kiss, hug, caress, touch, etc. Achieving a sense of God's agreement, heart-to-heart bond, like hunger and thirst.In this case, if you have sexual intercourse, both parties can have a satisfactory sex life.

(3) Sexual synchronization: There are obvious differences between men and women in terms of sexual desire intensity, speed and sexual pleasure. Generally speaking, male sexual desire is stronger, sexual impulse is easily aroused, occurs faster, and can reach orgasm within a few minutes.After ejaculation, sexual arousal subsides quickly.Women's libido is relatively weak, and the sexual impulse is slow to start, most of which take more than 10 minutes, and the libido lasts for a long time and fades slowly.In terms of sexual pleasure: male sexual pleasure has two contacts from the genitals, but female sexual pleasure has only one contact from the genitals, and the other two come from the contact of the whole body and spiritual and emotional satisfaction.Due to the sexual differences between men and women, both parties should try to make up the sexual differences, narrow the differences, and keep the sexual excitement synchronized during sexual intercourse.First of all, it is best for women to take the initiative to shorten the time of sexual excitement. Men should not rush to act, but prolong pre-sexual caress and intimacy, and wait for the female desire to be aroused and the vaginal opening to be lubricated before sexual intercourse.During sexual intercourse, the man inserts the penis into the vagina, twitches and rubs the vaginal wall back and forth, the movements should be light, avoid rough and violent movements, and touch the breasts or other sexually sensitive areas at the same time, so that the woman's sexual pleasure can reach a climax, so her face flushes and her breathing speeds up. Vaginal paroxysmal contracture, some women moaning, these uncontrollable performances are the sincere expression of female euphoria, and it is the continuous excitement period of orgasm, which is called the plateau period of orgasm in sexual medicine.Women can have two different orgasms during one intercourse. The orgasm of the vulva occurs when the clitoris is excited and is characterized by the spontaneous expansion and contraction of the vaginal opening.Uterine orgasm occurs after penile penetration and is characterized by rhythmic contractions of the uterus.Uterine orgasm usually occurs after vulvar orgasm. Experts report that this kind of deep orgasm only accounts for 10% of women, and it occurs after strong stimulation and full satisfaction.

Orgasm is a relatively brief phase of the sexual response.Men ejaculate when they enter orgasm. After ejaculation, the orgasm subsides. Female orgasm muscle cramps are more frequent and longer.The intensity of an orgasm depends on many factors: the type and intensity of sexual stimulation, the level of fatigue, psychological receptivity to sexual stimulation, and the degree of intimacy between the parties.If the orgasm is not reached, it often takes a long time for the sensitive areas of the genitals and the tension of the body to calm down, resulting in insomnia and irritability. Although it is not harmful to physical health, it seriously affects the mental and emotional state.If a man does not know how to provide further stimulation to his wife who has not entered orgasm, it will inevitably affect the relationship between husband and wife in the long run.Therefore, men should try to control the degree of stimulation during sexual intercourse, let women enter orgasm in advance, and do not pull out the penis immediately after ejaculation, and should further meet women's requirements and caress, so as to make sexual life harmonious and happy.

(4) Posture: A harmonious sex life requires a reasonable intercourse posture. There is no absolute distinction between good and bad intercourse postures. The choice of posture depends on the specific conditions of both husband and wife. The principle is that both parties feel comfortable and happy physically and mentally. Uncomfortable or forced positions are not advisable.

There are various types of sexual intercourse postures, which can be divided into three types: front entry, rear entry and side entry according to anatomical characteristics.

Front entry is a unique sexual intercourse posture for human beings, and there are many specific methods that can be used, such as standing, sitting, and lying.

The doggy style is a sex position commonly adopted by mammals, and it is also suitable for humans.The side-entry type is only suitable for the supine position, and it is often used for the weak or patients with certain diseases.Every couple should choose their sex positions according to their own preferences, and they should also change their positions frequently. This has certain positive significance for enriching the content of sexual life and harmonious sex life.

2.Moderate sex life is good for health
As we all know, a harmonious and pleasant sex life is beneficial to people's mind and body without harm. Sex life is a necessity for mental health. It has a huge hidden power.How to have sex life can be beneficial to health, and how to master the moderation of sex life?
(1) Frequency: Generally speaking, the frequency of sex life is determined according to different ages, different periods and the physical condition of each person.Newlywed period: Sexual requirements are more urgent, and the number of sexual intercourse is relatively frequent, once a day or several times a day; a few months after marriage, the number of sexual intercourse is relatively reduced, once every 2 to 3 days.Later, with age, sexual desire gradually weakened, and the frequency gradually decreased.Sexologists recommend that the frequency of sexual life is: once or twice a week at the age of 30, once a week at the age of 40, once a month at the age of 50, and once a month at the age of 60.Those with strong physique can be appropriately increased.In fact, since ancient times, many books have made time regulations on the frequency of sexual life. The real best interval should be based on the fact that the husband and wife do not feel any discomfort after having sex.After a moderate sex life: For men, the whole body is refreshed, energetic, refreshed, confident in work and study, without dizziness, weak waist and knees, weakness of limbs and other discomforts; for women, moderate sex life, smooth and delicate skin, Bouncy, bright hair color, charming appearance, even middle-aged and elderly women, will still have the charm.At the same time, the feeling of fluttering in sex life promotes neuroregulation and hormone secretion in women. The secretion of ovarian hormones, adrenal cortex and medulla hormones promotes breasts to become more plump.The pectoral muscles that support the breasts are exercised during sex, helping to plump and firm the breasts.So some people say that a harmonious sex life is a catalyst for female beauty.On the contrary, for women, excessive sex life may cause mental fatigue, light head-heavy, shortness of breath, loss of appetite, frequent urination, abdominal discomfort, low back pain, and increased leucorrhea.Therefore, moderate sex life is very important for physical and mental health.For a small number of couples who are physically strong and women are weak or women are strong and men are weak, the frequency of sexual life should be controlled based on the health of the weak.

(2) Time: 365 days a year, 24 hours a day, when is the most suitable time to have sex and is most conducive to physical and mental health?Many couples are very concerned about this issue. From the survey data of sexologists, most of them think that it is more beneficial to have weekends or holiday evenings.There are three main viewpoints:

One is that it is better to go to bed at night. The reason is that after dinner, the husband and wife should take a walk and chat appropriately, and then go to bed to have sex. The rest time can maintain abundant energy the next day.

The second is to sleep for a few hours first, and it is better to have sexual intercourse as soon as you wake up. People who hold this point of view believe that after a day of intense study or work, most of them are more tired. Laxity may not satisfy both parties.Take a nap first, and after a period of rest, your physical strength and energy will be restored.It is more conducive to sexual harmony to have sexual intercourse when you are physically and mentally strong, and a few hours of rest afterwards will not affect the work of the next day.

The third is that early morning is better, because after a night's rest, physical strength has been restored, and there is more energy in sex life.From the perspective of human physiology, the concentration of adrenal hormones and gonadal hormones is the highest around six o'clock in the morning.At this time, people's sexual desire is the strongest, and sexual intercourse at this time can enter a state of excitement in a short time and reach orgasm.

Exactly when is the best time to have sex, it should be decided in light of the work, study, physical and mental condition, sexual habits and preferences of both parties.

How long is advisable to have sex each time?Many couples often feel dissatisfied because the duration of sexual intercourse is too short in their sexual life.Especially the women are more prominent, they hope to prolong the time of sexual intercourse, and can fully enjoy the pleasure of sexual life.In fact, there is a huge gap in the duration of one-off intercourse. Some surveys have found that the average duration of one-time intercourse for healthy men is 6 minutes.The duration of sexual intercourse is affected by the following factors:

①Environmental factors: Couples should have a good environment when they have sex. No one can peep at them. It is difficult for others to hear the conversation. The environment is quiet and the lighting is soft.Both parties can feel the joy of sex with peace of mind and to their heart's content, and can relatively prolong the time to achieve sexual harmony.If the environment is not safe, children or the elderly are in the same room, and even outsiders are easy to interfere, not only the time will be shortened significantly, the quality of sex will decline, and it will even easily cause impotence, premature ejaculation or sexual psychological disorders.

②Physical factors: Sexual behavior is a kind of whole-body exercise. In the transfer of sexual organs, both parties have to exert more physical strength, mainly based on the posture of sexual intercourse. Whoever takes the initiative will consume more physical energy.In short, men consume more than women.If the degree of sexual intercourse is intense, the physical exertion will be greater, so those with strong physiques will last longer.On the contrary, poor physique lasts for a short time.

③Emotional factors: A harmonious sex life is based on love. If a husband and wife are in love with each other, they are like a duck to water in their sex life. Both parties will try their best to satisfy each other. Time, can achieve extended sexual intercourse time and orgasm platform period, fully enjoy the joy of sex.If on the contrary, the relationship between husband and wife is poor, one party is active, the other party is reluctant to cope, or the mood is unhappy and absent-minded, the time of sexual intercourse will be significantly affected.

④Experience factor: The duration of sexual intercourse is related to the accumulation of sexual life experience. When newly married or reunited after a long absence, both parties are particularly excited and will be triggered immediately. Often, ejaculation occurs within a few seconds of sexual intercourse.Especially both are the first time, and some even start to ejaculate before the penis is inserted into the vagina.For those who have a long sexual life experience, both parties can frankly explore and summarize the practical experience and lessons of the success and failure of sexual life, so as to grasp the characteristics of the other party, use their own consciousness and actions to control the other party, prolong the duration of sexual intercourse, and improve the quality of sexual life. .

Sex education

Sex education is an important part of sexual health care. Only with a comprehensive understanding of sex knowledge can we do a good job in sexual health care and guide people to enjoy a healthy and civilized sex life.Sexual life is one of the three major lives of human beings.There is an inevitable connection between material life, spiritual life and sexual life.Sex life is the foundation of human natural reproduction, without sex life, there would be no human beings.A scientist once pointed out: "All ignorance is regrettable, but ignorance about such things as sex is a serious danger." Sex is the driving force for the development of human history, and it is also related to social stability and everyone's physical and mental health and quality of life.Everything has its duality, and sex is the same. It can bring people great physical and mental pleasure, sublimate the relationship between husband and wife, make the family harmonious, the society stable, and the country prosperous.If there is no good sex education, people cannot fully understand sex knowledge, treat sex life correctly, and abide by sexual morality, then the family and society will be endangered, and at the same time, it will also be detrimental to the physical and mental health of individuals.Therefore, we must get rid of the feudal sexual awareness, carry out healthy and civilized sex education, so that people can accept new sexual concepts, abide by sexual moral norms, and accept the constraints of sexual morality and law while enjoying material life and spiritual life. Basically enjoy sex life to the fullest.
