Lets go down this route.
You are describing sex over and over despite being corrected over and over. I'm not sure why. It doesn't make you more right to ignore it.
In your case...
Man = XY
Woman = XX
What about XO?
What about an XY with complete androgen insensitivity (they have XY by they have large breast, great hair, and a vagina)?
So what would you call these people?Some people are born with a mixxup. And don't figure out until later.
