One small addition, that actually happened and relating to "Naturally Blonde"s post.
My ex and BFF never to my knowledge misgendered me ever in my presence - yet her speaking to our son on the phone the other day, referring to me: "Your dad is here, and HE wants to speak to you..."
I immediately noticed and later on asked her about it. She said: "Well, so you the dad... and dads are HE, or?"
I did not argue and try telling her that there just might be 'SHE dads', like maybe... SHE goats?
In any case, the point I try to make is, our situation is not ALWAYS completely, intuitively and instinctively obvious --- not even to ourselves says your UNCLE, err... AUNTY

Thank you for sharing,
