By confessing the AGP thing, I get the feeling that DH wants to be honest (I do think it's good for someone to be able to acknowledge that their transition was driven by AGP). But I also have a suspicion about something else (which others have eloquently pointed out) ...AGP is driven by boundary breaking. AGP creates a kind of high where the behaviour has to keep on escalating. At first it's wearing lacy underwear underneath clothes to work, then it progresses to 'being a woman' at home, then a woman full time, then getting access to female only spaces etc. In a way, what would be more perfect than being a fully confessed AGP, totally up front about it, and STILL being accepted by gender critical feminists? to go behind 'enemy lines' and be accepted by them, when you've admitted you are THE thing (a male with AGP) that gender crits criticise?
As Datun says, if this really is a fetish thing, and it's the main reason for DH's transition, then it's kind of messed up to still expect that we perceive DH as a woman. Because then the motivation isn't any kind of mental health care, or even just about feeling more comfortable...ultimately,the reason for the perception ties into his sexual thrills. It makes me feel like an unwilling participant. I honestly just don't see any good reason to acknowledge someone as a woman becuase they get a sexual kick out of it.
