Shyness is a sign of lack of self-confidence. It's also a style. At a certain age, when men and women are different, we are afraid of being seen by the opposite sex and being seen too clearly. As you get older, you will gradually find yourself and become better.
In addition, some men have reservations when they meet new members of the opposite sex. At that time, it was a kind of demeanor, which is usually the case with men with Pisces personality. But this shyness is not self-confidence, but a kind of "distance beauty"
