You have to understand that most men are raised to be stoic and to be the rock or cornerstone of their family. They are often socialised to be indifferent to their emotions and even encouraged not to show them no matter what, e.g. my dad showed no emotion when his mother died even though inside you could see he was hurting, but he was at the funeral supporting his siblings Also, men do not talk about emotions as frequently or in as much detail as women. Women might be ecstatic, happy, upset, sad, angry, depressed, jealous, down, frustrated or whatever. A guy is "not bad", and when we talk its only ever about how drunk we got the other night, or how good that girl at the end of the bar looks naked Society just doesn't cater for men that need to express their emotions.
Even though this attitude has changed somewhat as more and more, society recognises the physical side-effects that can come with bottling up one's emotions, it still permeates throughout society and the family unit in some form or another from fathers who were raised with these beliefs. It's kind of like how women were expected to be good housewives back in the day, like this:
...except men haven't had their "feminist" movement yet...gosh that sounds wrong
As for a more general comment, men aren't hard to understand. We're like animals really; when we say we want X, chances are we want X; we are happy with food, beer and tv; and it wouldn't hurt everyone once in a while if we got our balls licked (preferably by someone else )
