I think you`re being very unfair, Animeiac, with these stereotyping your making.  Biologically, a "man" is a creature that has the right equipment -- this "real man" stuff is cultural and behavioral nonsense.  Everyone's expectation of a man is different and it's unfair to not keep that in mind when stating these generalizations you are trying to make.  So, I think the proper question is not "what makes a real man" but more "where does a person gain thier expectations of a real man."  Someone mentioned that they learned from an example led by their father, but I think any strong male figure in your childhood is going to change your views on the expectations of a "manly man."
