Basically, what in your words, is your definition of what it means when someone is a real man, or an adult man? How does one attain being a man? And lastly, does becoming a man differ much from what it takes to be a real woman? If so, how so?

Note: This doesn't refer to any autonomic, biological changes such as puberty and physiological development. This only refers to voluntary choices an individual makes. For example, one might say being a real man involves becoming physically fit, while being a real woman involves looking sexy and curvy.
