3. Penile erection in children and the physiological and psychological characteristics of puberty.

Physiological basis of penile erection in children

A man's penile erection is often seen as a sign of sexual ability, and is conventionally considered to be something that occurs after puberty, seemingly unrelated to children. However, it is puzzling that some children also experience frequent penile erections. How can this be? To clarify this issue, it is necessary to describe the physiological process of penile erection in men.

It turns out that male penile erections are divided into two types: one is called psychogenic erection, which is closely related to various sexual stimuli from the outside world, such as reading certain books or magazines, anything that provides sexual stimulation can induce an erection. This type of erection is also closely related to one's own thoughts and imagination. Therefore, this type of erection only occurs in people who are aware of sexual relations between men and women, and thus it does not occur in children.

The second type is called reflex erection, which refers to erection caused by certain stimuli to the penis. These stimuli can be sexual stimuli such as tactile stimulation, which in turn induces psychogenic erection. However, sometimes erection can occur even without sexual stimulation. Any stimulation that causes heat or congestion in the penis can cause spontaneous erection. In this case, the erection is not related to the cerebral cortex and can also occur in children.

So, under what circumstances are children prone to reflexive penile erections? There are roughly the following situations: First, when the feet and lower body are covered with too warm blankets during sleep, or when using electric blankets, the penis becomes too warm and congested with blood, resulting in an erection.

Secondly, washing your feet or perineum with hot water before bed, especially soaking the penis and scrotum, will make the local congestion of the penis very obvious, making it easier for the penis to become erect when you go to sleep that night.

Third, dressing a child in tight-fitting clothes can cause the penis and scrotum to become constricted, and the warmth can induce an erection. Furthermore, tight clothing can create a compressive stimulation on the penis, resulting in a negative tactile sensation that can also trigger an erection.

Fourth, children frequently touch their penis and scrotum, or adults caress and play with them, often touching their genitals, which is also a reason for inducing reflexive penile erection.

Fifth, if a child has phimosis or redundant foreskin, coupled with inflammation caused by poor hygiene of the genitals, it can lead to pathological penile congestion and erection.

Sixth, some children with pinworms experience itching, and this stimulation can sometimes reflexively cause penile erection.

In fact, penile erections in children are not a disease. If it is due to conditions such as phimosis or redundant foreskin, it is advisable to have it surgically treated as soon as possible. If the erection is not caused by disease, it can be prevented by paying attention to daily life, such as keeping the penis area warm or wearing tight clothing. Knowing the above, there is no need to worry too much about your child's penile erections.

Sexual physiological and psychological characteristics and sexual hygiene during puberty

Physiological characteristics

Adolescence, simply put, is the developmental period. Biologically, it refers to the transitional period from immaturity to maturity, that is, the transitional stage from childhood to adulthood for a boy. During this period, the body undergoes a series of remarkable physiological changes.

The most obvious changes during puberty, besides the rapid increase in physical growth (height and weight), are the development of major secondary sexual characteristics (deepening of male voice, appearance of beard, etc.). Due to the rapid development and full maturation of the gonads and accessory organs, puberty is characterized by sexual development and maturation, accompanied by changes in thoughts, intelligence, emotions, and behavior.

The age of onset of puberty, the rate of development, the age of maturity, and the degree of development vary greatly among individuals. This variation exists not only between ethnic groups and between males and females, but also within the same sex and race, and even under similar environmental conditions. In my country, the age of puberty is approximately 11-12 to 17-18 years old. Boys who develop secondary sexual characteristics before the age of 9 or who lack any signs of puberty after the age of 14 are considered to have abnormal sexual development; the former is called precocious puberty, and the latter is called delayed puberty.

In terms of physical appearance and secondary sexual characteristics, males lag behind females by 1-2 years. However, in terms of the development and maturation of the gonads, there is almost no time difference between men and women. Yet, the process of maturation differs between the sexes. After entering puberty, the prostate gland begins to develop, secreting fluid and resulting in the first nocturnal emission. In the early stages of nocturnal emission, there are no sperm in the semen, indicating that physical development is already in a slow phase. During puberty, the testes and penis of males develop and enlarge rapidly, the male gonads mature, and sperm production begins, indicating that fertility is achieved. Studies have found that sperm can be detected in the urine of 13-year-old boys.

The physiological changes during male puberty are generally divided into five stages, with the development and changes in the reproductive organs being the primary focus.

The first stage is called pre-puberty, which lasts from birth until the testes begin to develop during puberty. During this period, changes in secondary sexual characteristics are not yet obvious.

The second stage is the period of significant enlargement of the testes and scrotum. This occurs approximately between 9 and 12 years of age, during which the scrotum turns red, skin folds increase, and short, fine pubic hair appears on the external genitalia.

The third stage is the period of significant penile growth. During this time, the penis becomes noticeably longer, but the increase in circumference is less pronounced. The testes and scrotum continue to enlarge, pubic hair increases, and armpit hair and facial hair begin to appear. Voice also begins to change. This period mostly occurs between the ages of 12 and 15.

The fourth stage is the period of further development of the genitals. The main changes at this time are the further enlargement of the penis and scrotum, the darkening of the scrotum, and the full development of the glans penis.

The fifth stage is called sexual maturity. At this time, the external genitalia have developed into their adult form in shape and size, and the pubic hair is distributed in an angular pattern.

For most men, it generally takes 3 years to go from stage 2 to stage 5, but a few may take as little as one year or as long as 5 years.

In addition, the skin on the chest and forehead, as well as the areola, of young men is darker than that of young women. Sebaceous gland activity increases throughout the body during this period. The voice gradually begins to develop into a male voice around age 14. The Adam's apple grows rapidly only after the penis has stopped growing rapidly. The development of all secondary sexual characteristics takes approximately two years to complete.

The rapid changes in the various parts of the body, especially the development of sexual organs and sexual function, have a significant impact on children's psychology, emotions, spirit, and behavior.

Psychological characteristics

The arrival of puberty marks the beginning of a boy's development into adulthood. They will become individuals with mature sexual and reproductive functions, capable of procreation. However, as male characteristics become more prominent and mature, they will also experience a series of psychological changes related to sex. Therefore, understanding these changes is extremely important.

First, the formation of male sexual psychology is closely related to the development of his sexual awareness and the impulses of his sexual instincts. We know that the most important aspect of puberty development is the significant changes in gonadal function, with sexual function gradually maturing. That is to say, at this time, a man's testicles and scrotum begin to enlarge noticeably, and he experiences nocturnal emissions. Furthermore, under the stimulation of sex hormones, his physical appearance undergoes a series of changes, such as a prominent Adam's apple, muscle development, the growth of facial hair, a lowering of voice, and a taller stature. With the increase in male hormone secretion and the rapid development of sexual function, they begin to strongly realize the differences between themselves and women and their relationship with women. At the same time, they experience some special psychological experiences, arousing sexual impulses and beginning to pay attention to sex. For example, they may feel ashamed of the changes in their sexual characteristics. Some men feel nervous and fearful about their first nocturnal emission, and dare not talk about it to others, resulting in a heavy mood and mental confusion. In fact, the emergence of sexual awareness and attraction to the opposite sex due to sexual maturity are normal phenomena during male puberty.

In their relationships with women, boys typically experience two phases: a period of aversion and estrangement, lasting approximately six months to a year. During this time, boys are particularly sensitive to differences between themselves and women, often adopting a cold, reserved, and evasive attitude towards them. For example, high school boys might rush out of the classroom as soon as class ends, leaving the girls inside until the bell rings, at which point they return to their seats. The next phase is a period of intense attraction towards women. After overcoming aversion, boys become unusually eager to approach and please women, especially during group activities. They will go to great lengths to attract women's attention. Boys who are usually indifferent to their appearance suddenly become concerned with their looks and try to emphasize their masculinity. Some boys even mistakenly believe that bad habits like smoking and drinking are signs of manliness. The final phase is a period of romantic love, where long-simmering, secret love is revealed. At this time, they concentrate their affections on one woman, significantly reducing their relationships with other women.

In short, the strong sexual desire and impulses experienced during puberty are normal psychological and physiological phenomena during development. Parents, teachers, and society should understand this characteristic, provide patient puberty health education, and closely observe subtle changes in their mental state, personality, and behavior, taking timely and appropriate measures. It is crucial to avoid subjective authoritarianism or laissez-faire attitudes. Because boys at this stage lack knowledge about sex and proper guidance, they are prone to behavioral mistakes and even turning to crime. Therefore, parents and teachers must pay special attention to children during this period and help them smoothly navigate puberty.

Sexual hygiene

1. Sexual hygiene during puberty

During puberty (15-20 years old), sexual organs develop rapidly and tend towards maturity, leading to the onset of nocturnal emissions. However, the age of first nocturnal emission varies from person to person, generally around age 16. Because some teenagers lack sex education and do not understand that nocturnal emission is a normal physiological phenomenon, they mistakenly believe it to be a pathological condition. They are both ashamed to talk about it and filled with doubts, which can affect their studies and work. At this time, it is important to introduce them to relevant sex education and some basic knowledge about puberty development.

Furthermore, the curiosity generated by seeing their own enlarged penis leads to constant hand stimulation and pleasure. To achieve sexual satisfaction, they may then masturbate uncontrollably. Over time, this becomes a bad habit that is difficult to break. At this point, they should be made aware that masturbation not only causes significant psychological harm, but also, due to factors such as unclean fingers, can lead to inflammation of the genitals, which in severe cases can affect their marital sex life.

2. Sexual hygiene during the honeymoon period

After marriage, men often experience excitement and impulsiveness, which is normal. However, it's crucial to remember that sexual intercourse is a collaborative effort between both partners. Always respect the bride's wishes and only engage in sexual activity when she expresses sexual desire. Especially during the first sexual encounter, the woman may be very nervous, so the man should be extra gentle, considerate, and affectionate. During intercourse, both partners should concentrate and avoid being hasty or rough.

Generally, female orgasm is experienced more slowly in terms of both arrival and subsidence, while male orgasm is experienced more quickly. Intercourse should begin slowly, with the expectation that both partners will reach orgasm simultaneously. It's rare for both partners to experience harmony and satisfaction during their first sexual encounter; therefore, learning some sex education before marriage is essential. This not only helps establish a normal sex life after marriage but also provides the right mental preparation for occasional sexual failures, preventing future sexual dysfunction and psychological barriers caused by an unsuccessful first sexual experience, and even avoiding damage to the marital relationship.

During first sexual intercourse, the woman's hymen will rupture, causing mild pain and a small amount of bleeding. At this time, sexual intercourse should be stopped for several days to allow the wound to heal.

For a destination wedding, choose a clean hotel. The bedding should be clean. It's best to use your own clean sheets or towels on the bed. During the trip, change your underwear frequently and shower often to maintain cleanliness. Due to travel fatigue, reduce the frequency of sexual activity.
