Well then, here's mine.
My story is a little odd for a lot of reasons... some things might not connect right (some I still don't understand, and others I would prefer not to share...) so I'm sorry for that. : P Anyway!
I'm a jaguar therian, so acting animalistic was never unfamiliar to me. I ran around on four legs far, far longer than anyone else I know of did (9-10 is when it faded out). I could walk, sure, but I didn't like it as much. I preferred my four feet over my two. And, of course, I would RP animals all the time. I always wanted to be the animal - always. Jungle Book was one of my favourite things to RP, and I had a large collection of plastic animals that we would create intricate stories with. As soon as I could draw, I would make up animals and draw those. I also drew anthro animals constantly. Good times.
When I was 12, two things happened. I awoke to my therianism. It wasn't a big thing to me. It explained what I'd been going through forever, as well as showed me that I wasn't alone. I liked that... I would wear cat ears and tails often, and I hennaed jaguar spots onto myself in the summer. It was partially out of a desire to be inhuman, and party out of a desire to bring myself closer to my life totem - also the jaguar, oddly. The other thing that happened was I had my first RP character that was a part of me. Her name was Krystal, and she was an anthro fox.
A lot of stuff happened between 12 and 16, but suffice to say that it helped in its own way. I had been wearing my animal apparel often, been drawing them quite a lot and really been a furry all along. And then I joined my first furry community. I knew about the furry fandom - I just had to admit it to myself first. So I joined, and I fell in love. It was another group of people kind of like me!
And I'm still here today.
Still, it took a good deal of... Well, luck, really, to find my fursona. I'm not a very... easily represented, if you will, person, even with all the options the furry community offers. So, while I loved a great deal of the characters I had, I rather gave up on ever having a real fursona. About a week after I'd given up, I drew something in English class. A catboy, sort of. More importantly, a *Cheshire* Catboy. And from there, things just fell into place. It was really nice, finally being able to say "Hi, I'm Alcide - a Cheshire Cat." And, of course, now I know what sort of costume I want to make!
