Yes. I'm sure.

It would be one thing if we were performing certain tropes, as like the aforementioned bower birds courtship dance as sex rituals for procreation purposes only.

But we're not. It's all the time, for social acceptance outside the behavioral mechanisms surrounding copulation.

Hate to break it to you, but very very few of us spend more time each day banging that we do other things, like eating, sleeping, working, caring for our children, pursuing hobbies, etc.

Why do I or anyone else have to do any activity not related to sex and copulation as appropriately proscribed "feminine" or "masculine" or risk social censure? Especially when I have zero interest in fucking anyone I'm doing said non-sex activity with, anyone watching said non-sex activity, or who thinks their dumb ass opinions on sexuality should have a say on my complete disinterest in performing elaborate courtship behaviors when I'm clearly not courting?

Further, it's pretty much proven that without social gender pressure from infancy, there's a lot more overlap in hobbies and skills that occurs naturally, when children are left to their own devices and skill trained without bias.

A lot of women enjoy building things and wrenching. A lot of men enjoy needlecrafts and cleaning/cooking.
