After children enter adolescence, they begin to develop rapidly and their bodies will undergo obvious changes. Boys and girls will quickly develop height and other developmental changes, boys and girls will also develop secondary sexual characteristics, boys will have nocturnal emission, and girls will have menstruation. At this time, the children's bodies are undergoing significant changes, but their psychological development is relatively much slower. Adolescent children are easy to fall into the confusion of youth, so proper physiological education is necessary. In order to avoid embarrassment, we can explain physiological knowledge generously and naturally.

When boys and girls enter puberty, their sex hormones are vigorous, their bodies develop rapidly, boys become tall and powerful, Adam's apple, beard and secondary sexual characteristics begin to develop, sexual organs begin to develop, sexual impulses begin to sprout, and nocturnal emission will occur. Girls also began to grow taller, sexual organs began to develop, and menstruation appeared. Adolescent children have a hazy yearning for the opposite sex. At this time, children lack experience in facing these changes and should be guided by adults.

In order to avoid embarrassment, fathers can teach their sons and mothers can teach their daughters. It is the only normal way for people to tell their children. Don't be too nervous and don't care too much. It is better to let nature take its course. We should ensure a good attitude and habits of work and rest, and focus on learning and beneficial spare time activities. Boys and girls communicate normally, neither too close nor too far. The communication between adolescent boys and girls is necessary and normal.

When children are faced with physical confusion, they can explain it in plain words, but they should also be guided to resist bad temptations and live an active and healthy life.
