Anger is the only emotion many men allow themselves to express. Growing up, we are taught to avoid anything that is seen as the least bit feminine. We are taught that men 'do' while women 'feel.' We learn to keep all emotions under wraps, to see them as unmanly. We cannot show we are hurt, afraid, worried, or panicked. The feeling we are allowed to express without being called feminine is anger. When men experience IMS, anger is often the primary emotion.
