What determines gender? What is a "woman"?

What makes us recognize someone as a "woman"?

---

Cute, pretty, beautiful, sparkly, shiny, fluffy, slender, moist, pink, pastel, sweet, soft, long eyelashes, big eyes, thin legs, bright red lips.

Adjectives, onomatopoeia, touch, color, smell, appearance. We live by finding fragments of the "feminine" in these various elements.

The most accurate distinguishing factor would be the "biological" sex difference.

Uterus, pregnancy, childbirth, menstruation. Only women have these. In other words, this is the essence of women. Is that really the case?

There are women who have lost their uteruses for various reasons. Not all women become pregnant or give birth, nor do they want to. Some people don't have menstruation, and some stop it with prescriptions such as the pill. Also, did you know that there are men who have become pregnant and given birth?

We judge a person subjectively, picking out their superficial elements. This behavior is almost always unconscious. And there's nothing bad about it. However, in a society where diversity is respected, we need to know just how "diverse" "diversity" really is.
What is a woman? What am I?
