It's rather chilling how AGP has been whitewashed out of the dialogue. When I first googled it several years ago, it was quite openly talked about, but gradually it's been denied, denied, denied.
I have seen the most convoluted attempts to justify it. From claiming that all women have it. That we get aroused when we put on skirts, tights, jodhpurs (yes jodhpurs), etc. Saying it's exactly the same as when a woman looks in the mirror and thinks she looks good before she leaves on a night out. Utterly confusing admiration, with arousal. And evolving into claiming that when women are looking forward to a hot date, they might get a sexual tingle, and that is them feeling aroused about having sex 'as a woman'.
There are numerous sites devoted to it, however. It's pretty difficult to deny, when you can see the individuals themselves swapping stories.
Miranda Yardley, a transwoman (not AGP). talks about it.

One of the characteristics of AGP is the arousal one experiences by forcing people to accept one as a woman, despite overwhelming evidence to the contrary. (Unlike those with gender dysphoria, who do their level best to pass).
Boundry violation is part and parcel of the fetish. They are usually heterosexual (attracted to women), hence 'male lesbian' and the insistence that lesbians sleep with them last they be considered transphobic, despite the presence of a penis.
You can pretty much bet that if a transactivist is demanding access to women, getting violent about pronouns, is an older male, and attracted to women, they're AGP.
There have been numerous studies, the most famous of which is Blanchard's. But you will find him villified the community. However, his results have been replicated with a few minor criticisms.
