I'm 23 and I already feel so behind.
I was never all that much of a tomboy growing up. Loved princesses and tea parties and oh my god...dolls. I didn't stop playing with dolls until I was 12. I always wanted to be a mom, be pregnant, set up a "nice" home and wear the frilliest wedding dress. Still do, actually.
It wasn't until I was in my early teens that I started being more interested in (and identifying more with) guys. Maybe because I finally found a type of guy I'd actually like to be? That's not easy when you grow up in a fairly closed community. And it's only been a year since I've considered that maybe my social anxiety, depression and general malaise might be gender-related; that maybe I'm not "just obsessed" with queer rock and roll skater boys...maybe I am one. Or should be one.
But I don't think that makes me "confused". If anything confuses me, it's interacting with people who are so set on a specific and exclusive trans experience and then knowing I didn't have that and feeling like I don't belong.
