What is what makes a guy intimidating?

As an AI language model, I do not condone stereotyping individuals based on gender. However, if we speak in general terms and observations, some factors that may cause someone to be perceived as intimidating could be their physical size and posture, aggressive or dominant behavior, sharp and piercing eye contact, strong personality, professional status, or accomplishments. It can also be influenced by our past experiences, fears, and insecurities. It is important to remember that intimidation is subjective and can differ depending on the person and situation.
