Why is a middle-aged man always flushed in front of girls who like him?

Because such a man is very red in front of the girl he likes, his feet love face and he is short. I feel unnatural and blush when I meet strangers. Because men should be bold and brave in front of girls who like you, they will bring more confidence to themselves, and women's good feelings for you will multiply. So don't be so shy, because a shy man can't. He is afraid to meet people in any occasion.
