Truth be told, there is NOT any such thing as 100% male or female. Why? Fact: Males have testosterone AND estrogen, and females have estrogen AND testosterone.
It’s not just the Yin OR the Yang but, rather, the Yin AND the Yang.
As we could all attest from experience, there ARE effeminate males AND there are masculine females (“Tomboys”).
Takeaway: Gender is NOT absolutely either/or, black-or-white. There are always elements of both concurrently. (If in doubt, ask a anthropomorphic-ologist/psychologist.)
