Women are experts at sharing their feelings and men are known for keeping theirs in check.
Boys grow up learning that they are supposed to be tough and independent. All this toughness and squelching of feelings is too bad because men never learn how to be vulnerable.
Women want to get close to men but it's hard if a man is so tightly sealed that nothing can open him up short of dynamite. An intimate relationship, by definition, involves sharing of feelings and emotional honesty, so if a man can't be anything except in control at all times, (or aggressively angry) then he isn't going to have the best possible relationship and his wife or girlfriend isn't going to be very happy.

There is such a thing as emotional intelligence and it's a relatively new area of psychological research. Basically it's the ability to figure out, acknowledge, and deal with your own and other people's emotions. Studies have shown that this kind of ability is much more important than high IQ in determining professional success. So there are multiple payoffs to being in touch with your feelings.
So what's an emotionally-strapped man to do? It's hard to change a lifetime of not expressing your feelings, but not impossible. There's one book I know of that can help.
1000 Questions for Couples, by Michael Webb gives concrete questions that help each partner learn about each others feelings and emotions.
