A lot of people in this thread really, rrally don't understand women much better than the troons do.
Women frequently seek a lot of social validation and approval; if you're in a social circle where being "sex positive" or kinky is considered mature, progressive, smart, and exciting, a woman will absolutely claim a mild kink/fetish to signal her membership in the group. (Men also signal group inclusion, just usually in different ways, since men and women tend to communicate differently.)
When a woman says she "feels sexy", what she is saying is NOT that she feels aroused by herself, nor even that she feels aroused at all. She is saying "I recognize that I am sexually attractive to men, and therefore feel confident, desirable, and have worth." If she ia aroused, she's aroused by the idea of men wanting her. Aka not self-aroused, nor aroused by het underwear itself, nor the "meaning" of the underwear. She's aroused by the idea that a man she finds attractive would also be attracted back. You know, like a normal healthy sexual human connection.
When a woman even literally says "I turn myself on", she is not being literal, you absolute acoustics. She is using a turn of phrase, a jovial metaphor, which gets social approval for being a fun confident person. Just like saying "I'm too sexy for my shirt" doesn't mean you are literally planning to strip in public.
AGPs feel aroused by the concept of fulfilling their idea of what a woman is, which is typically over-simplistic and stereotyped. This is why they're aroused by shit like breastfeeding, knitting, or wearing tampons. (It's also why their clothes are fucking tacky.) Sometimes women report a lot of confidence and satisfaction when fulfilling feminine gender roles... Wise troons will claim that's how they feel too, not aexual arousal, but spend 5 minutes on troon reddit and you can see they're lying.
(Personally I'd be okay with AGP TVs, as long as they admit their motivation and stop this "real woman" bullshit.)
By the way, it eas probably already mentioned, but "autoandrophilia" (aka women turned on by the idea of being men) was only ever theorized and never researched, because the researchers never discovered any. We obviously are now seeing a correlate of course (the fujoshis-gone-wrong). However it's worth mentioning that at least one (I think it was Blanchard) noticed the exact same thing we've pointed out repeatedly on this thread -- female troons are NOT aroused by being manly, and often don't even try to be, they avtually want to be "a gay man" specifically. Their longing and/or arousal is specifically at the idea of being a gay man. (Blanchard suggested some new term for it.) So it's interesting and worth noting there still doesn't seem to be an actual autoandrophile - females don't turn themselves on.
Also note, even lesbians don't turn themselves on, and will often be like "ew" at themselves even while buried in pussy.
