Perhaps femininity is a more specific concept than masculinity. I call this the "Mrs Pac Man Effect".

It is more common for people to personify objects (say, a rock or a frog or a random internet user) as male than female. In many languages, the plural for a group of things is male even if it only has one male element.

A simple charachter like pac man is male in a universal kiki/bouba sense, but the female equivalent needs a bow (it is a more complex specalization of its male counterpart)

Obviously, biologicially male-ness is a specialization of female-ness, because females more resemble unsexed creatures in their ability to reproduce.

But in the latent space of the human mind, or in language I think male is closer to "default" and female is a specialzation of maleness. Even the words female or woman are modifications of the word male or man.

Perhaps this evolved out of primative social structures. If women occupy a more domestic social role and men a more nomadic one, then you would encounter more men in the outer world. So you would generally associate unknown things in the external world as being masculine, and would associate feminity with specific inter-village inter-family things of your local world
