Acronym for autogynephile, and that seems to mean what TheImpossible1 stated.

This is what "RationalWiki" states:

Autogynephilia is the name given to the pseudoscientific hypothesis that transgender women who aren't exclusively attracted to men are transitioning purely as a result of a fetish for being viewed as females. This covers lesbian, bisexual, asexual, and pansexual trans women. The term translates from Greek to something like "self-woman-love," with the intended meaning "love of oneself as a woman."

First time I've seen this site (top search result), and it has the rainbow colors icon for its Sexuality category.
