Many people mistakenly think that when learning to swim, coaches and students will have physical contact, and many parents do this when teaching their children. In fact, if you really learn to swim, the coach can also explain and demonstrate. Therefore, your male classmate offered to teach you swimming, which can be divided into two parts to analyze the problem. First of all, is he a good swimmer? If not, then you can refuse on this ground; If he is really good at swimming, he will really teach you. If you want to learn, I suggest you try to learn. However, it should be noted that when beginners practice in the water, they should choose the height of the water around their shoulders or a little shallower, so that you can stand alone at any time during the practice to avoid any unexpected movements of boys. In addition, if you don't want to arouse other people's thoughts, it is recommended to choose a more traditional and compact swimsuit, such as flat feet and low chest. You study it several times, and it's not hard to see each other's real motives! ! I wish you a happy study! !
