I'd say it's you, but that's just me. To my mind there is no way an adult can be a teenager, with all that lack of basic experience, socialization (positive or negative, in any way), never paid a bill, great hope, huge disappointments, everything so intense.
I just don't buy into a healthily adjusted adult feeling that way like an adolescent does. Yes, hormones are everywhere, but with the serious benefit of adult socialization. The amout of non trans adults who say 'I wish I could go back there with my brain/life experience now' is striking. To do it all again with an adult brain and the wisdom of adult perception, well that'd be bloody brilliant really, wouldn't it?
They can't do it. We can (to an extent), as long as we don't kid ourselves we are actually teenagers. Because we aren't on any level. Nobody really has that luxury, trans or not. It would an absolute luxury, a fantasy of a dream adolescence that nobody ever gets to live.
That is not the generation we come from, we have no idea what it is like, and they have no idea what it was to be a teen however many decades ago. Even superficially, the hopes, the fears, the mores, the music, the television, the aspirations, even the fashions that defined male v female. Very few of them fit or even merge for any generation or the sub groups within each.
Look at the early 80's with everything from later punks to New Romantics and Sloane Rangers. How would you explain that to a teen now? It was barely understandable to those of us who were teens in the 90's and only then because it wasn't as far back as hippies or mods & rockers, and we knew people who were identifiably still in each group.
To say you're a teen equivalent now is self indulgent flattery as far as I can see. And it's not even that flattering because realiy, who would want to be one aside from the fantasy of doing it all perfectly? As I say, everyone has that glorious hindsight, trans or not.
