That we lack the language to describe perfectly the state, is a reflection of our position within it. As Karrie pointed out, there are aspects of traditional femininity that many men now accept as their own.
Perhaps it's just a step in the evolution from manly to humanly as our species takes on a wider spectrum of roles in productivity. We're adapters and to find a solution to fit a need like becoming nurturers, for example, is simply the process at work.
The exact same thing can be seen within the feminine gender of our species, in taking on the traditional male aspects that make for a successful, for example, predator. A quality that assists in turning desires into instincts that are beneficial in competition.
So I think we can see it in both genders if we care to look objectively, and though we rely on the traditional language to describe the changes in our world, it's apparent that new words are added to that lexicon while others drop off due to lack of use or becoming less descriptive than a new word or another word.
Manliness is a state of transition within the evolution of our species?
