For example, I have a colleague who is male, but he usually wears makeup and foundation, and his clothes are more exquisite than girls. His legs are really thin, but when I saw his picture before, he was a little fat and black. Then we asked him why he is getting thinner now. He said that he usually goes on a diet and does some exercise. Eating less greasy food will make you thin. In fact, boys will be thinner than girls. In fact, I think this is also their personal preference and pursuit.
But if we see such boys in our life, we will be kind to them. There are strange ideas that they are girly, and some people think that they have problems with their sexual orientation, so they don't understand them. But I don't think there should be such a performance. After all, this is also their personal hobby and pursuit. Actually, it's quite difficult to lose weight. There is nothing wrong with being strict with yourself and making yourself better and better, so don't talk too much about others when you see such a boy.
However, some boys are born thin. For example, there is a boy in our class who is so thin that he can't get fat no matter how he eats, and his hands and feet are very angry. He also wants to change his reminders by gaining weight, but these are difficult to change because of innate factors.
