Great China is the home of Confucius and Mencius, the country of etiquette, with five thousand years of traditional culture. Since the old life of teaching and educating people is to “do not speak, do not listen, do not see”. So in this country of sex talk, who dares to put sex on the table to say ah? So when it comes to sex, whether it’s family education or school education, it’s always a case of the parents and teachers wanting to talk about it. From the moment a child is born, we start to pay attention to its physical development. It is clearly written in science books that a child can raise its head, grow teeth, roll over, sit, crawl and walk in a few months. These are the laws of the child’s physical growth and development, and we follow these laws, quietly watching the child grow up day by day, full of joy. But also, there are certain rules for the sexual development of children, when do children masturbate? When does a child start to pay attention to gender? When do children start to pay attention to the body of adults? When do children start to ask themselves where they come from? When do children like to be with friends of the opposite sex? Do you know all these things? When my son was almost 3 years old, he used to touch the birds with his hands. Every time he touched them, his grandma would scare him with a sullen face: “Don’t touch them, you little rascal, they’re dirty ……”. I saw and laughed at grandma and said “later when he touches again you pretend not to see, give me okay?” The grandmother half-heartedly “you will spoil the child, not properly educated when small, grew up to become a small rascal!” I still smiled. When Daidian once again did not shy away from people touching the little birdie, I calmly asked him: “Does the little birdie hurt?” ”No, mommy.” “And does Birdie itch?” ”No, Mom.” “And when you touch it, are you comfortable?” ”Yes, mommy” my son said happily and nodded his head affirmatively. I still calmly said “son, the little bird can touch, but you must wash your hands, not to hurt it, but also to go to your own room and close the door to touch, not to let others see, understand?” ”Got it.” After two or three months, Daidian almost stopped touching Birdie Birdie. The sexual development of human beings is roughly divided into five stages, namely: 0 to 1.5 years of age, the oral period, 1.5 years to 3 years of age, the anal period, 3 to 6 years of age, the genital period, 7 years to puberty, the latency period and puberty. 0 to 6 years of age before the child’s sexual activity is characterized by “self-centered”, they always focus on their own views And action, only focus on their own sexual feelings, do not pay attention to the surrounding environment on the evaluation of their behavior and reaction, showing the state of “self enjoyment”, thus showing the infantile state of sexual development. For example, children rub, pinch their legs, touch their genitals, etc., without avoiding others. Many parents do not accept the child’s infantile stage of sexual development and feel shame and anxiety in the face of the child’s sexual activities such as leg clenching, masturbation, rubbing, and sexual games, scolding and even intimidating the child. Children generate pleasure through exploration of the body at this stage, which is equivalent to shoving everything into the mouth when they are much younger. If parents fail to guide the child correctly at this stage and take an incorrect approach, the child will become confused and disoriented as to why the parents have to strictly prohibit something they enjoy so much. When exploring again the child will develop fear, helplessness, anxiety, shame, and even guilt. They don’t know what to do, which in turn will have an impact on their future lives. It is recommended that parents first have a basic knowledge of the laws of their child’s sexual development. Understand the basic rules of children’s sexual development, and give full respect to the child’s behavior, so as not to sow hidden dangers for adult psychosexual health. Second, parents should be guided by the behavior of their children. When we intervene in the child’s sexual activity, we can target the child’s sexual behavior and tell the child the boundaries of sexual activity. Let the child understand and follow the rules, such as touching the birdie bird or pinning legs can only be done in their own room. A healthy sense of shame allows the child to know how to comply with the sexual rules and sexual morals of human society. Third, parents must not shame and scold their children. If parents shame, intimidate, scold and scold their children because of their sexual activities, such behavior will hurt the child’s sexual psyche and lead to an unhealthy sense of shame about sex. In turn, this will cause the child to repress and depreciate his or her sexual desires, leading to shame and unease when the child is sexually aroused, sexually emotional and sexually pleasurable in adulthood, and laying down psychological or physical hazards for the child’s sexual activities in adulthood.
