Enby (pronounced: ehn-bee) the soundnof the letters N-B for nonbinary.
I define enby as a person who does not identify as a man or a woman. Some also include people who identify as both a man and a woman. I find doing that unnecessary however.

And that’s not what autogynephilia is. That is a debunked hypothesis where a straight MAN becomes sexually aroused at the site of himself as a woman.

Transwomen are not straight men who want to be women because they admire them so much or because they are sexually aroused at the idea of being a woman.

I think you might need to do more research.
