I consider it has to relate to the situation, circumstance, or the case that you are crying and it is hard to generalize all the conditions to dictate if it is proper or not. Noneless, in most case, women are easy to attract attention by crying in some of the Asian society yet men would be thought as a chicken and hardly get essential support by cry only.
