Meh. Maybe I'm being hard-hearted, but all I can see are the contradictions, and the blatant conclusion that this boy is not trans, he's AGP.
"You’re fairly sure your skin has always been a problem."
When I read that, I expect mentions of things that go back all the way to childhood. Instead:
"The very earliest sign was swimming. Or clothes in general, really, but swimming was the easy one. When you swam, you always wore (and always still wear) a shirt, even though the males of your family don’t. More broadly, you refuse to ever be seen without one. You called it modesty, but now you know it as shame. Shame for your square-ish, flat, slightly hairy flesh prison."
Little boys don't have any more hair on their chest than little girls. In fact, little boys are no different in the chest than little girls. So this is not about being a little boy; it's about being a teenager already. And that's his earliest sign?? Nothing about hating his genitals at 6? Nothing about wanting to wear dresses at 8? So much for "your skin has always been a problem".
"The most obvious sign, a little later than the swimming, was video games, and your refusal to play as a male. “Girls look better!” you might have said. "
Later than the swimming, so definitely into teenage years. Nothing - nothing - about childhood.
"The first time you showed off a bit – wore a sports bra, showed some skin – there was so much joy that it scared you."
And now we get to the outright contradictions. He won't be seen without his t-shirt on, but he's ecstatic to "show some skin"? Where is the logic in there? Or is it that he's showing skin in a sexualised manner? And that overjoys him? I can well imagine that - if he's AGP.
"You stay up late with your best friend, and they help you find a name,"
I notice how he carefully doesn't mention the sex of said best friend...
" There was peace in your lack of self, in not realising why you’ve slowly, unnoticeably grown addicted to skirts and long hair and bare strips of skin."
Again with the fact that those feelings weren't always there, that they grew when he reached puberty.
"Your safety, your peace, has been torn down so slowly you didn’t even notice, and now everything hidden behind it has come rushing out. Everything you were has been torn out and you don’t know how to rebuild yourself."
That's the exact opposite of an "always been trans" experience! Every single word in there screams, "I was fine until I reached puberty."
"Terrified, because now you know what you are, and that knowledge is like an anchor with a too-short chain. Fine when you kept it up, but now you’ve let it drop, and it’s tugging you down with it. You were afloat, and now you’re drowning, and you don’t know if you’ll ever surface again."
Indeed. That's exactly how I would expect someone discovering they have a sexual fetish to feel.
This boy needs to sit down with Dr Hakeem and learn about AGP. Transitioning may make things worse so he needs to be caught before he goes too far, for his own good.
