I am also male, and there are some reasons why some men don't want to---the "unwritten rules" that men are taught at a very early age and, perhaps surprisingly, enforce among each other. As part of my own addiciton recovery work, I started reading Mark Greene, who has written about this "man box culture." The short version: society has a pretty narrow definition of what it means to "be a man," and stepping outside that definition is often met with derision from the adults in our life when we are children, and the other men in our life when we are adults. That is a very powerful force that can "box" us into a role that is a caricature of our inner selves. In particular, appearing "feminine" (in this case, in the form of caring for others) is often met with strong disapproval from a handful of other men with status, and we respond to it.
