First, a correct understanding of gender issues is a common sense of life that children must know when they grow up.
It is precisely because we have been seriously influenced by traditional conservative ideas since childhood that we always avoid these problems. Many parents will choose to avoid when their children ask relevant questions, and some even scold their children for not letting them know these things. The normal common sense of life is like something shameful. In fact, if parents or teachers face these questions, they will not only help children answer or even avoid or criticize, but also stimulate their curiosity, so that children may go to some point of no return because of curiosity for several months.
Second, people will become more and more open in the future.
In fact, comparing our generation with our parents and grandparents, we have been greatly liberated on the basis of their thoughts. Grandparents seldom fall in love. There were child brides at that time. If prostitutes are unmarried, they can't run around. They spend most of their time in the boudoir, but when their parents start to fall in love, many questions about the sexes are still very obscure. Until our generation, both boys and girls, are much more open, and have a more or less understanding of the physiology and psychology of the opposite sex, but not to the point of discussing gender issues at any time as usual. But I firmly believe that people will be more and more open in the future, and one day there will be content in textbooks to teach children to correctly understand and treat gender issues.
Therefore, I think it is only a matter of time before the knowledge of sex education appears in textbooks, because this is the basic physiological needs of people. We should look at this problem with an open mind. There is nothing shameful to know about it, and nothing is the greatest shame.
