Uncharacteristically, I'm of the opinion that this is fairly close to a fine question. :)
The title change was absolutely necessary; we don't do survey questions, and this shouldn't be answered as a survey question. But in most of its other details, it's in precisely what I see as the most pragmatic, answerable type of Stack Exchange question:
I tried to do X; I got stuck against problem Y; how do I solve this.
Certainly the question is making very simplistic assumptions and broad generalizations; but, well, that's what OP's question is.
I think the question could be improved, for this focus. The "Wouldn't you--" survey-style questions could be converted to something more on the lines of "I think a man would do , my friend says they never would".
And the ending - "Make me understand the mind of a man!" is indeed broad and unanswerable. But tweak the last bit to "I thought love, sadness and anger are universal feelings that everyone has regardless of their gender; but how do I square that in my writing with the sense that men conceal their feelings entirely, or don't feel that much to begin with?", and you have an extremely answerable question.
I've just made an edit along these lines, and you can tell me if it appeals.
