There are several changes in boys after puberty, which need the attention of children themselves and parents. The first is the change of sound, because we can't see the vocal cords, but the sound can be heard. His voice gradually changed from a very immature voice, like a girl's voice, to a man's voice. In the meantime, if it is not well maintained, it is called dumping. If your voice is broken at this time, it may affect your life. I worked as an educator at school. I used to be a propaganda team, because children at this time were naive, lively, impulsive and active in everything. At that time, they often went out to perform, so some children liked to take part in this activity. If they are willing to go out to perform, they will be very unhappy. We will let them play, and there will be some solos during the performance. They all want their own voices. Some children try their best to be brave, and finally their voices are broken. They used to be a good performing artist, but they had to give up this career because of their poor voice. After puberty, children are more impulsive. Of course, every child wants to have a chance to express himself. This is good, but pay attention to protect yourself.

Other changes are not easy to hurt ourselves, such as the appearance of armpit hair and body hair. We can directly find the appearance of Adam's apple when taking a bath. Therefore, as parents and children themselves, when they find that they have these changes, they should pay attention to their own changes and protect their physiological reactions. Of course, there are boys who have nocturnal emission on the phone. There will be a requirement of * * *, which was said to be * * * before. Now we say * * *, there will be such a request. When these needs are often affected by this * * *, this demand will suddenly appear. As a kind of protection, we should avoid being influenced by this * * *, because this * * * is meaningless, and it is still young until they reach adulthood. This kind of * * * had better not be accepted at this time. Of course, there are many picture books, books and some posters on the joints now, all of which are for children to see, so you can only protect yourself by your own efforts and try to avoid these * * * things, then your sexual impulse may be less.

2. Adolescent physiological knowledge

Adolescence Gobler China Psychological Hotline Adolescence refers to the stage of individual sexual function from immaturity to maturity, and biologically refers to the transition period of human body from immaturity to maturity, that is, the transition period of a man from childhood to adulthood.

During this period, my personality is mature and I can have children. It can be seen that adolescence is mainly divided into stages of physiological maturity, which overlaps with the stages of life divided from psychological or social aspects.

In the stage of human growth and development, adolescence accounts for half or even more time. At present, there is no consistent age range in various countries, which generally refers to 13, 14-17 and 18 stages. Psychologically, it is also called pre-adolescence, which is equivalent to the middle school stage in pedagogy and is characterized by rapid physical growth.

In addition to adolescence, adolescence will last until the age of 25-30. Because the sexual maturity of men is about one year later than that of women, it can be determined that the puberty age range of men is 14- 18 years old.

1~2 years too early or too late is normal. Men of this age are usually called boys, while women of the same age are called girls.

In adolescence, there are not only obvious physiological changes, but also great psychological changes. Physical growth with sexual maturity as the main content has a great influence on the psychological and social aspects of teenagers, forming several important characteristics of this period: adolescence is a transitional period, and adolescence is a period for individuals to transition from children to adults.

Usually, people clearly distinguish between adolescence and childhood, and the dividing line is sexual maturity. For men, the sign of sexual maturity is * * * (usually * * * when sleeping at night, that is, nocturnal emission, but there are also * * * *); Women have menarche, that is, the first menstruation.

The physiological development centered on sexual maturity makes teenagers have obviously different social and psychological characteristics from children. Individuals depend on adults in childhood, and adults constrain and decide the main contents and aspects of children's lives and activities; Children are not responsible for their actions.

With the increase of age and the complexity of life scope and activities, teenagers have different characteristics from children. They gradually have a certain intention and sense of responsibility, and decide how to carry out certain activities by themselves.

You should bear certain criminal responsibility for your actions, especially some criminal acts. But teenagers are also different from adults.

Although they have some independence, they are not completely independent; In many ways, especially in material life, we have to rely on our parents; They have not yet become fully responsible persons and are not criminally responsible for all their actions. It can be seen that this transitional state between children and adults makes teenagers become marginalized people in sociology. The uncertainty of their identity and the uncertainty of social demands on them have caused many special mental health problems.

Adolescence is a period of development. Adolescence is the period when human development is completed. Research shows that there are two stages in a person's life: the rapid growth of the body and the significant changes in the proportion of various parts of the body. One is in the prenatal period and the first half year after birth, and the other is adolescence.

The rapid growth and development of adolescence is called the phenomenon of rapid growth of adolescence. In fact, this phenomenon begins before or at the same time as sexual maturity and ends six months to one year after sexual maturity.

The rapid growth of men began at the age of 10.5- 14.5, peaked at the age of 14.5- 15.5, and then gradually slowed down. By the age of 18, the height has reached a fully developed level, and the weight, muscle strength, shoulder width and pelvic width have also increased. For example, while women are experiencing external changes such as menstruation and secondary sexual characteristics, the reproductive organs gradually mature, the vulva begins to appear, and the endocrine of * * * begins to increase, the uterus becomes larger, and the follicles in the ovarian cortex begin to develop at different stages.

Everything shows that the transition to sexual maturity has begun. Due to the physical and sexual development, it has a great influence on the psychological characteristics and social life of teenagers, which also produces a series of mental health problems.

Adolescence is a period of change. Adolescence is the most rapid and obvious period of physical and mental changes of teenagers. During this period, men are divorced from the characteristics of children in terms of body, appearance, behavior pattern, self-awareness, communication and emotional characteristics, and outlook on life, and gradually become mature and close to adults. These rapid changes will make teenagers have mental health problems such as confusion, inferiority, anxiety and even bad behavior.

Therefore, adolescence is a predictable and unpredictable period. That is to say, in this period, the development of people from children to adults is predictable, but what will happen or what problems will occur in the development process is unpredictable.

Adolescence is a period of resistance. In the early days, Charlotte Buller, a famous German child psychologist, once called adolescence "a period of passive resistance". This name has been used to this day.

Due to the gradual development and maturity of body and mind, individuals often take a negative and rebellious attitude towards life during this period, denying some good qualities they have developed before. This rebellious tendency will make teenagers resist other requirements and norms of parents, schools and social life, which will lead to some mental health problems that are not conducive to their social adaptation.

Adolescence is a period of heavy burden, and all kinds of obligations and responsibilities are borne by adolescent men. Judging from the problems they have to deal with, adolescence is also a period of heavy burden. Adolescence is a transitional period. Teenagers should gradually undertake some tasks undertaken by adults, and the environment may constantly hand over some things handled by adults to them, which will increase their burden, but these burdens are indispensable for their maturity. If they are not burdened, they will not mature in the future.

Adolescence is a developmental period, which determines that they have to deal with various changes and problems brought about by the maturity of height, weight and muscle strength. Especially when they are sexually mature, their psychological pressure increases relatively fast. Adolescence is a period of change, which determines that they must gradually establish while abandoning all kinds of naive concepts and behavior patterns.

3. The knowledge that boys must have in adolescence

When a boy enters adolescence, all parts of his body will change.

Physiologically, such as: acne, beard, bone thickening, voice thickening, sexual organs began to develop; Psychological aspect: I began to have a good impression on the opposite sex, no longer so obedient to the wishes of parents and teachers (psychological rebellion), my curiosity increased, and I began to become sensitive and suspicious, and my mood was prone to fluctuation and anxiety. How do you accept this sudden change? Facing a brand-new self, how do you adapt? Relax, this is what all boys have to go through when they grow up.

The following points will remind you. I hope it can accompany you through this growth process like an amulet and let you grow up safely and smoothly. First, the problem of "face" When the first acne poked out from the horizon, when you woke up, you suddenly found a circle of furry moustaches around your lips.

They "destroy" the smoothness and cleanliness of your face. Do you feel like you can't see anyone? Some boys take some extreme measures because they can't accept it at the moment. Acne grows, squeeze it, beard grows, pull it out.

Don't you know it's dangerous? Acne will naturally scab and fall off when it is cooked. If squeezed, the bacteria on the hand will not only infect the acne area, cause inflammation, redness and even pus, but also leave ugly scars and cause lifelong regret.

Besides, boys' beards should be shaved off rather than pulled out. The human face, especially the mouth and lips, is called the "danger triangle", which is the most susceptible place to infection with germs. Even shaving should be careful to prevent scratches and illness, not to mention pulling out the beard.

The destruction of hair follicles will directly lead to skin lesions. Therefore, we should happily accept our appearance.

In fact, whether you have a beard or acne, it will only make you look more masculine. What's wrong with that? B, timely treatment of the "sanitary corner" male scrotum and its adjacent parts have many wrinkles, great elasticity, rich sweat glands and exuberant secretions, which are often soaked in urine and urine, sweat and * * * *, so bacteria, germs, exfoliated cells and dirt are easy to accumulate. When the body's immunity is reduced, tinea cruris, dermatitis, eczema, dermatitis, dermatitis, etc. Will happen; In addition, bacteria can also enter the urinary tract from the urethra, causing urinary system infection.

There are many tiny sebaceous glands at the junction of man's foreskin and head, which can continuously secrete yellow oily substances. Often mixed with urine and skin desquamation, it becomes cheese-like scales and accumulates in the coronary sulcus. If you don't clean it often, it will cause inflammation, redness and pain of the foreskin, and even cause foreskin adhesion or foreskin stones.

According to scientific verification, skin scales contain a carcinogen, which can induce cancer in men. For the above "sanitary dead corner", it is necessary to "clean" every day to ensure the hygiene of sexual organs and external organs and prevent some diseases.

C. pay attention to what you hide. Medical research shows that the temperature requirement of male reproductive system is better than its body temperature. Because the temperature is too high, it is not conducive to the production and survival of * *.

So pay attention to the "small environment" here. First of all, you can't take a bath with overheated water.

Especially not taking a sauna. Some boys think that hot water can kill bacteria, so when local discomfort occurs, they wash it with hot water.

Don't you know that it is very harmful, which will greatly reduce the survival rate of * * and even cause infertility and sexual dysfunction in adulthood. In addition, * * * should change frequently, and don't wear those polyester and blended ones.

Should be replaced with soft cotton * * * to keep the lower body dry. Also, wearing jeans every day is not suitable for developing teenagers.

Because jeans are generally thin and tightly wrapped around male genitals, the local temperature will be too high. Moreover, jeans are thick and hard, and wearing them for a long time will cause certain friction to the genitals, especially when the weather is hot and the climate is humid. D. About "sexual impulse" First of all, "sexual impulse" is normal and healthy, and it is a growing phenomenon.

Some young men and women who don't understand that this sexual feeling is a normal phenomenon of biological growth will feel shy or afraid. This is unnecessary.

Learning how to deal with these feelings and decide your own sexual behavior is also part of becoming an adult. Adolescent men develop rapidly physically and psychologically. Sometimes erections, nocturnal emission and other phenomena are really caused by "sexual impulse", but at other times these phenomena occur naturally and have nothing to do with sex.

Of course, some "sexual impulses" are caused by external factors, such as watching pornographic movies and books. This phenomenon is not what we advocate.

As long as they are properly guided, such as participating in sports and group activities, their "sexual impulse" will be alleviated. After the influence of time and process, most people can adapt to these sexual feelings and learn to integrate into other aspects of life.

E, * * *, not too much, but not too much. After puberty, it is often inevitable that boys will have * * * behavior. Moderate * * * can make people vent, without harm to themselves, and there is no need to feel inferior or guilty about it.

Appropriate * * * has been accepted and recognized by more and more people. This kind of behavior is a sign of cherishing oneself. However, there is a limit to everything. If the genitals are congested for a long time and are in an erection state, it will cause sexual dysfunction, prostatitis, prostatic hypertrophy, impotence, premature ejaculation and inability to * * *.

4. What health should adolescent boys pay attention to?

Male adolescent health care mainly treats spermatorrhea, redundant prepuce, phimosis, cryptorchidism and * * *.

1. Scientific treatment of nocturnal emission and * * * nocturnal emission refers to the phenomenon of * * * that occurs without * *, which mostly occurs when dreaming at night, so it is also called "wet dream". The nocturnal emission that occurs while awake is called "nocturnal emission".

There is not much difference between them in essence, and they are both normal physiological phenomena. The first nocturnal emission usually occurs after the appearance of * * *, armpit hair and upper lip beard, and in the later period of the year when the body grows fastest.

According to the survey, the age of the first spermatorrhea of boys at present is mostly 14~ 15 years old, and the youngest is 1 1 year old. 17- 18 boys, more than 90% have had nocturnal emission.

Nocturnal emission is a natural physiological phenomenon that regulates sexual function. If sexual stress is not removed, it is easy to accumulate, making people nervous, irritable and uneasy.

Nocturnal emission can relax and relieve sexual impulse, thus achieving physiological balance. Normal nocturnal emission is not harmful to health.

However, many young people are still worried about nocturnal emission. They regard * * * as "vitality", which is the most precious essence of human body.

Others think that they are not married yet, and it should be that "Yuanyang has not vented", and spermatorrhea has vented "Yuanyang", which is physically deficient. These wrong ideas confuse many men.

Whenever they suffer from nocturnal emission because they are nervous before taking part in sports competitions or exams, they will not only feel ashamed, but even feel guilty, resulting in fear, anxiety and uneasiness. Some students are under too much psychological pressure because of nocturnal emission. They want to drop out of school and lose confidence in their beautiful youth.

These ideas have no scientific basis. In fact, in addition to * * * and a small amount of protein, fat and sugar, the main component of * * * is water.

The total amount of * * * discharged at a time is only 3~5 ml, which is insignificant for the * * * produced and discharged by a man in his life, and there are no problems such as "vitality" and "Yuanyang". Moreover, it is not true that some young people only discharge urethral gland secretions from the urethra when they are sexually impulsive, or discharge prostate secretions when they are asexual.

Therefore, it is not unusual for normal unmarried young men to have spermatorrhea 1~2 times a month, or even more than a few times, so don't worry. On the contrary, worry and fear have a much greater impact on the body than nocturnal emission itself.

There are also some young people who are often uneasy about not having nocturnal emission and are afraid that their sexual development is not good. Actually, it's not.

* * * can be discharged into the urethra in small amounts for many times, and discharged with urine, which is not easy to be noticed by myself. First of all, we should learn sexual knowledge, relax, divert our attention to slow down the sexual excitement of the brain, consciously ignore the sexual scenes in obscene books and movies, establish a normal work and rest system, and actively participate in various cultural and sports activities.

Second, we must be temperate. Excessive youth is also easy to cause nocturnal emission.

In addition, it is necessary to maintain the hygiene of reproductive organs and avoid local adverse effects of reproductive organs.

5. Physical knowledge that boys must know

1. Proper cleanliness can keep the male reproductive system healthy. If the cleanliness is too much or not enough, it will have an impact on the health of reproductive system.

If you don't pay attention to cleaning, it is easy to cause prostatitis, epididymitis or foreskin inflammation, especially if the foreskin is too long and phimosis. You should always remove scales from your skin to reduce the chance of cancer. 2, control the number of sexual life The skin of the reproductive organs is very delicate and vulnerable to external damage. If you have sex too early, it may induce reproductive problems in adulthood, such as sexual dysfunction, easy aging, backache and so on.

In addition, frequent sexual life will make the reproductive organs in a state of congestion and edema, which will reduce their physiological functions and make them prone to prostate-related diseases. Young people's sexual life can reach 2~3 times a week.

Men have * * *, which is a normal physiological phenomenon and a manifestation of sexual maturity. Don't be too nervous because of * * *, but control the frequency of * * * once a week. If you often * * *, it will make the urogenital system congested for a long time, and the local immunity will decrease, which is easy to induce seminal vesiculitis, prostatitis, habitual premature ejaculation or erectile dysfunction and impotence.

3, carefully clean the foreskin * * * Because the inner plate of the male foreskin is relatively fragile and sensitive to chemical cleaners, it should be partially cleaned with water. If you wash it with shower gel or soap, it will easily cause allergic reaction of the foreskin.

In addition, it is easy to deposit a lot of scale on the foreskin. If it is not cleaned in time, it may reduce the defense function of local skin tissue and be susceptible to infectious pathogens. Turn the foreskin over in the bath to remove all the accumulated sebum and dirt.

4. Maintain good living habits Men should quit smoking, because harmful substances in cigarettes can cause arteriosclerosis, hinder local blood circulation and easily cause impotence. In addition, it is necessary to reduce the riding time, because the bicycle seat is hard and the front of the bicycle is prominent. Riding for a long time will cause nerve damage, and even lead to the wear and tear of seminal vesicle and testis.

Warm reminder, men should learn to relieve stress, and don't sit on the soft sofa for a long time, which will increase the local temperature of testicles, thus damaging the spermatogenic function. Go to the hospital for physical examination regularly to rule out the possibility of urinary system diseases.

6. Who has some knowledge about boys' puberty?

"Sexual fantasy" is also a natural phenomenon, and most teenagers will have it. Whether there are sexual fantasies is not necessarily related to whether teenagers' minds are pure or not and whether their behaviors are moral.

Many teenagers suffer from uncontrolled thoughts and "sexual fantasies", which are even unnecessary. The reason why teenagers have sexual fantasies is not only the hazy germination of their own sexual psychology in adolescence, but also the expression of a little knowledge of sexual knowledge and a lack of self-control ability for sexual impulses.

"Sexual fantasy" is the instinctive reaction of teenagers after they know their gender roles, and it is the prelude to the primitive sexual impulse of adolescence. It is a normal and common psychological phenomenon for adolescent boys and girls to like fantasy.

This is closely related to their psychological development and psychological growth. Sexual fantasies gradually germinate on the basis of special tendencies when boys and girls are sexually mature.

Sexual fantasy originates from all kinds of infatuation and fantasy about a certain opposite sex, is an instinctive impulse to the opposite sex, and an emotion that longs for the care and communication of the opposite sex, which is often completed in fantasy. Its uniqueness lies in its bright color, interest in sexual knowledge, curiosity about the physiological structure of the opposite sex, mystery about the reasons for childbirth, and then its affection, admiration and yearning for the opposite sex. In social occasions, I am nervous and excited because of the appearance of the opposite sex, and pay attention to my charm to the opposite sex. I really want to play a gender role in front of the opposite sex.

Sexual psychologists summarize these psychological activities as "sexual attraction". The association of these behaviors is called "sexual fantasy".

Sexual fantasy is temporary and self-controlled, and the dreamer can clearly realize that its content is illusory. What doesn't exist in real life is dominated by subjective will.

Girls should know more about their sexual fantasies, and the self-awareness of adolescent girls is gradually strengthening. They began to pay attention to designing and expressing their own image by dressing up, thus attracting the attention of others and the envy of the same sex. However, when their efforts fail to attract the attention of others, they often get psychological satisfaction through fantasy. In fact, sexual fantasy is a kind of psychological compensation.

Adolescent girls are in their developmental stages. Due to the secretion of estrogen in the body, there are secondary sexual characteristics such as * * * uplift, menstrual cramps and high tone. These physiological phenomena make them begin to have sexual consciousness, and with the popularization of film and television and rich social activities, their puberty appears ahead of time, and they begin to capture sexual knowledge and produce sexual fantasies. The affectionate scenes in movies, the language in novels and the intimate actions of lovers in parks will all cause their inexplicable sexual fantasies.

Fantasies, including sexual fantasies, are possible for every normal person. Appropriate sexual fantasies are understandable. It is a reasonable catharsis of adolescent psychological needs, without side effects and negative effects. However, fantasy should be moderate, especially for boys and girls in the flower season. If you just blindly fantasize, especially indulge in sexual fantasies, you will be in a trance, affect your study, work and life, and be harmful to your health. As boys and girls, we should correctly study habits, understand sexual morality, be civilized, and be self-respecting.

Self-control, focus on study and work.

7. Physiology of adolescent boys

A boy wrote: "When I got up that morning, I suddenly felt very cold in my abdomen. I thought I wet the bed. This is a shameful thing. I 15 years old. I touched it with my hand and found it sticky and uncomfortable at all. "

A week later, it happened again. I thought I had some kind of disease. Check it carefully. It is white and thick, like milk.

I'm so scared. I'm on tenterhooks all day, as if I'm going to die. Later, I couldn't bear the pressure of death. I told my father about it. Hearing this, he immediately widened his eyes and accused me of being thoughtful and not studying hard.

But I study hard during the day. I really don't think about anything when I sleep. I just sleep with all my heart. "Yes, yesterday seemed to be a pure boy. Today, abnormal and unpredictable changes have taken place in the body. The development of adolescence came without saying hello, which caught many unprepared boys off guard.

Due to the lag of sex education, the lack of sexual knowledge and the improper guidance of parents, some boys, like that boy, will feel uneasy at the first nocturnal emission. Some of them have been infected with the bad habit of * * * since then, and some people are depressed because of it. In fact, the experience of nocturnal emission by boys, like menarche by girls, is an important "milestone" in the process of sexual development, which marks the beginning of the development of male reproductive organs and is a normal physiological phenomenon in boys' adolescence.

Adolescence, when boys don't want to, will happen; And before puberty, no matter how you want to break your head, it won't happen. In other words, nocturnal emission is an unconscious reflex activity, which is not affected by human will.

The nocturnal emission usually starts at the age of 12 to 14. The sexual organs in childhood are basically in a state of deep sleep, and even if the child is naughty and active, there will be no * * *. Because with the onset of puberty, the hypothalamus begins to move, secreting a series of hormones to urge the pituitary gland to secrete gonadotropin, which commands the testis to work, making it produce * * * and secrete testosterone.

Testosterone not only makes the testis mature and produce * * *, but also makes the organs closely related to * * * *-epididymis, seminal vesicle, prostate and so on. Common development, even the vas deferens, * * tubes, urethra and other pipelines ready to transport * * *, are thriving. The seminal vesicle and prostate secrete the liquid part of * * * *, and the testis produces * * *, which constitutes * * *.

When * * * reaches a certain amount, the body can't hold it, so it will be automatically discharged, which is why boys will unconsciously discharge sperm. There is also a case of nocturnal emission, that is, wearing tight pants and washing feet with hot water before going to bed. When sleeping, the lower body is too warm, which will cause congestion of sexual organs, or inflammation of urinary and reproductive organs, such as dermatitis and prostatitis. It can also cause congestion of sexual organs, thus inducing nocturnal emission.

Therefore, nocturnal emission is a kind of * * * activity without * *. Wet dream is called wet dream when she sleeps and dreams, and nocturnal emission when she is awake. The appearance of nocturnal emission varies from person to person. The late appearance of nocturnal emission does not mean that * * * is produced late, because sometimes * * * may be discharged into the urethra many times through a small amount, which is often not easy to detect.

As for the frequency of nocturnal emission, in general, it is normal to have it more than once a month, once a week, or once every half a month, as long as it is not more than twice a week, so don't worry. However, not all boys will have nocturnal emission. As long as the reproductive organs are normal, it is normal to have spermatorrhea or not.

Of course, although adolescent boys are sexually mature, their sexual psychology is not mature. Therefore, while respecting the fact of their physical development, we should also pay attention to guiding them to cultivate healthy sexual psychology and morality, avoid reading unhealthy books, magazines and movies, participate in conscious cultural and sports activities, change bad hygiene habits, and wear loose clothes when sleeping to avoid excessive pressure.

Usually wear pants that are too tight and airtight, because the testicles are extremely sensitive to temperature. Often wearing tight pants will make the scrotum skin thicker, and the testicles will bulge as high as the inguinal outer ring, resulting in the temperature of the testicles being higher than the normal temperature, which will affect the development of the testicles. In addition, tights increase the friction on the head of * * *, and cultivate the habit of cleaning * * *, removing dirt and replacing * * *.
