you bring up an interesting point, I am not sure if potentially men or women are necessarly better comunicators than one another but I think that women have easier access to the ability for a couple of reasons.
1. Biology, it is a known fact that the female brain is better coordinated between its two hemispheres than the male brain is. That means that in a female visual info, emotions and other sensory experiances are more quickly desiminated and then expressed by woman than men.
2. Social. Women in this society have been much more condtioned from youth to express themselves and verbalize, the addtional practice over time gives women the edge in many cases
The above of course are generalizations with exceptions of course.
