@freemo It might be easier once people realize that everybody starts out destined to be female. But because of the information in their chromosomes (or rather, the lack thereof, especially in the Y-chromosome), the XY-people (let's not delve in the more than 2 chromosomes now) get a larger amount of testosteron, turning them into males.

But... sometimes that genetic information is borked, so you do have XY-people with feminine traits or XX-people with masculine traits.
And then you have people who are just inbetween. Not enough of this, not enough of that.
So, even though we're usually being thought that there is only 'male' and 'female'... it's in reality 50 shades of sex. 😋

But eh, that requires reading or watching educational programmes. That's too much effort to most people. Science is scary, y'know? :P
