Teacher: Today we are going to discuss a topic together, which is a very youthful topic. The male genitals are divided into two main parts. What are they? External and internal genitals.

Boys: Will men die without testicles?

Teacher: Nothing, no testicles?

Boys: People without testicles?

Teacher: For example, you know the eunuchs and the transvestites, right? They remove their testicles, so these people won’t die. But he was sterile and his life was short.

Boy: Why?

Teacher: Because he has an endocrine disorder, he cannot secrete male hormones normally. Only after the (male genitals) are perfected can he produce sperm, have his own offspring, and secrete male hormones. Then we can What can he do? He has a long beard, a strong throat, and strong muscles.

Boys: Will the testicles become larger or smaller as the temperature changes?

Teacher: It should be said that the testicles will become larger or smaller, and just to protect them, the scrotum will become larger or smaller. So now I will tell you, never wear underwear that is too tight. Wearing underwear that is too tight will make you look sexy, but make no mistake, it is not good for the development of the testicles.

Boys: What can you eat to replenish sperm?

Teacher: Healthy men have better health. I don’t think you need to worry about the number of sperm. It should be said that it is enough. The key is the quality of the sperm. When you grow up and get married in the future, you should be a Dad, at that time, you have to exercise well, increase nutrition, and make the number of sperm reach a certain standard. The amount of sperm that should be contained in every milliliter of semen should be 200 million sperm per milliliter. It's 200 million, which is normal. If the number of sperm per milliliter is less than 5 million, it is not easy to conceive. If the amount of sperm per milliliter of semen is less than 2 million, it is male infertility. Do not drink a lot of alcohol or smoke, otherwise it will be impossible to conceive. Give birth to a healthy, smart and lively baby.

Boys: Will excessive ejaculation affect your health?

Teacher: It means that the number of nocturnal emissions is high, right? We will talk about this issue soon. Nocturnal emissions should be a very normal physiological phenomenon. Generally speaking, there is no uniform number of nocturnal emissions for unmarried men. Normal standards, but if the frequency reaches this level once a day or several times a day, or if you have a little sexual desire, the semen will flow out

And after a nocturnal emission, you will obviously feel depressed. Inability to concentrate, backache, leg weakness, dizziness, headache, etc., then this is what we call frequent nocturnal emissions. What are the consequences of masturbating too much? Excessive masturbation will also cause frequent nocturnal emissions. Frequent nocturnal emissions will make you pay attention. Inability to concentrate, memory loss, listlessness.

Boys: How to avoid masturbation?

Teacher: What he said is very good. I think you should not think about it. It is better if you have not had such an experience. If you have such an experience, you must first say that it is a bad habit. You may now want to know how to avoid it. I say nocturnal emissions are normal, but frequent nocturnal emissions are abnormal. Then you need to find a urologist to examine and treat you. This is one aspect. The second aspect I think is that when you wear underwear, don’t wear it too tight, and don’t cover it with a quilt that is too heavy. Male students should also pay attention to keeping their external genitalia clean. If the external genitalia is not clean, they will Stimulates the external genitalia to produce nocturnal emissions. Secondly, I think you should not be overly addicted to or interested in sexual issues. Don't read those pornographic books, pornographic magazines, newspapers, movies, and TV shows, and you shouldn't browse pornographic websites, because you are now You are still young and have poor self-control, right?

Boy: Yes.

Teacher: Have you ever visited pornographic websites?

Boy: No.

Teacher: I once knew a student. He was very painful. He told his mother that I read a book that was a bit pornographic. After reading it, he said he wanted to get it out of his mind. He couldn't even go out, he just thought about that thing and couldn't concentrate. He said he regretted reading such a book.

${FDPageBreak}Boy: Why?

Teacher: Because if there is such a strong sexual stimulation, the sexual excitement of the cerebral cortex will be enhanced, and what kind of situation will it lead to? I will think about it day by day and dream about it at night< /p>

Boy: I would like to ask if women have frequent menstruation. Under normal circumstances, if there is no illness or disease, it should be once a month?

Girl: Teacher, I saw in the newspaper that a senior classmate in high school was about to take the college entrance examination. She had her period that day, so she took the contraceptive pill.

Teacher: She takes birth control pills, right? I think this should be under the guidance of a doctor. Under normal circumstances, we do not use this method to advance or delay menstruation. Normally this method is not used. The vagina is an organ for sexual intercourse, and it is a channel for menstrual blood to flow out and a channel for fetal delivery. There is a hymen on the outside of it, right? right.

Boys: What is the use of hymen?

Teacher: What is the function of the hymen, right? The hymen is in the vagina. It should be a thin layer of membrane with a hole in the middle. After a girl gets her period, menstrual blood will flow from it. The hymen flows out from the hole, but this hymen should be said that unmarried women generally have a hymen, but some women's hymen is very thin. After strenuous exercise, her hymen has ruptured, so the hymen is not The only measure of a woman’s chastity.

Girls: Will my hymen be broken when masturbating?

Teacher: I don’t think so. If it’s like having sex, it should be broken.

Boys: Will it hurt if her hymen is ruptured during sex?

Teacher: It should be a little bit, a little painful.

Girl: What is the difference between a hymen ruptured during sexual intercourse and a hymen ruptured during exercise?

Teacher: Same.

Girl: Does getting popular at marriage mean that the hymen is ruptured?

Teacher: Yes, yes.

Girl: Some magazines say that the hymen can be repaired. If it is done, what is the difference between it and the original one?

Teacher: We all know that the hymen can be repaired, and there is not much difference, but you have to know that what cannot be repaired is life, youth, and chastity. What cannot be repaired is the soul. It can never be repaired, and furthermore, the occasional sexual intercourse once or twice still has a huge impact on women's psychology, so I think men and women should protect themselves well and not treat this casually. The problem is not to be tried lightly.

Boy: I would like to ask if a girl can get pregnant only if she has sex during her menstruation?

Teacher: This is a good question. You generally cannot have sex during menstruation, definitely not. This is unhygienic and prone to gynecological diseases, which will definitely not lead to pregnancy. When will it be easier to get pregnant? During the ovulation period after menstruation, what we call the ovulation period, you cannot have sex with anyone casually. I hope that everyone can go through adolescence smoothly and smoothly. You must become more and more mature mentally and physically, because a person should be able to control his own behavior and should control his behavior rationally and know what to do. What not to do and when to do it, I think this is very important for everyone.

Students: Stand up and salute! goodbye teacher!

After class, the children left the classroom. The teacher said that this class also educated her. In addition to these textbooks, the children also learned a lot of other knowledge, and their schoolbags contained not only With these books on mathematics, physics and chemistry, their knowledge structure is more diversified, and how much do our parents and teachers know about this situation?

Teacher: I feel that some things are difficult for me to answer. For some things, I think they know a lot of things through many other channels. Our sex education is still lagging behind, because children actually I already know a lot of things in class, I think it should be very necessary to carry out, and students are still very interested. After telling them these things, they feel that it is nothing. We already know, we already understand, and you Guide him to divert his attention to other aspects, and teach him what to do, when to do it, how to do it, or what stage is not suitable for doing. He still knows. I think it is unfair to be honest. Said it would be better.
