What do you think a man is?

An adult human male.

A man is a protector and a provider and treats his lady like a queen. A real man takes care of his kids, both financially and by spending time with them. A man stands up for what he believes in. A real man always does what is right, no matter how difficult it is.

There are so many "prerequisites" to being considered a man by society, whereas a woman only needs to experience the onset of menses.

A human being who has a penis and/or identifies as a man.

A male who lives by a code of honor.

An adult person of a certain sex who wants to be perceived (and perceive himself) as that sex. A man can also be identified as a biological female undergoing gender reassignment.

Everything else re his behavior and demeanor is irrelevant in that men and women are (and should be) assessed re their character and actions rather than artificially socially ascribed stencils of what people are told they should or should not be due to gender, sex, sexuality or personality.

A man is a gentleman, confident, attractive, and strong.

He isn't afraid to spoil a woman and treat her to nice things, he listens to her and makes her laugh.

That my friend, is a true man :)

Some are fantastic gentlemen and human beings, some are criminal or addicted losers.
