What is the role of a man?

Depending on what type of man you're interested in the role of a man can be different but from most people i know and for me myself one of the # 1 rules is to just be there for her don't be ashamed of her. if you see her give her a hug or a kiss on the cheek or something. don't act like you don't know her in front of your "guys" if you like her like her in public and in private
