(ugh, this is so out-of-order and makes NO sense, but here goes)
Specifically trans? Just a couple weeks ago. I've had really bad body dysphoria for years and years now, and only recently came to terms with the fact that it's not been my (->-bleeped-<-ty) life causing it, but my actual body... after a very long process of dealing with the effects of said (->-bleeped-<-ty) life and resolving a lot of residual crap from that. Even though the problems are at peace, I still couldn't handle my body; it was a really bad source of anxiety that I'd somehow 'missed something'... that I hadn't exorcised that one demon, so to speak, that lingered and made me hate my body so much.
All the way back as far as I can remember, I wanted to be 'genderless'; to rip out my female-reproductive-organs (and sew it shut afterwards); but it's only over the past year and a half or so, with a wonderful partner, that I've come to terms with the idea of 'physical intimacy' and realized that I was 'missing something', so to speak.
A little embarrassed, that I had been very obviously lesbian (from the age of 7 or 8, I remember admiring female bodies) and never had learned what 'trans' was; despite causing massive amounts of trouble at school in a conservative place trying to start a GSA and getting a bunch of people together to do 'Day of Silence' and other sorts of events.
I always just honestly figured I was different or broken. It's... indescribably nice to have a more positive way to look at things.
