I've met several otherwise very nice guys who had this very issue...they had no idea what it meant to actually communicate (heck my cousin is like this). Sure everyday chatter is one thing but like in all relationships (siblings, parents, etc.) it is also just as important to be able to sit down and talk seriously...that is where they just had no idea how to. While some women are bad at this too it is primarily men who really seem to lack in this department.
