What i first thought i was
It's come up a few times here and there, but heres a more direct approach:
What kin type/s did you think you were before settling on your current one? Maybe go into a bit of why you thought so and what later changed your mind. If your still uncertain, what are you leaning towards or from and why?
For myself, i thought i was giantkin (i had no clue of the terminology at the time, though). I didn't get the draconic portion till around puberty. But before that i came to the conclusion that i was a totally giant and waited for the day i would physically grow into my soul (keep in mind, i was 6). I had dreams that i was truly bigger, my spiritual essence felt as though it was far from being contained within my body, and would shift into the mindset of something much larger then i truly was (it could be quite a ridiculous sight to see me act on these notions).
I then went on the buy clothing that might fit me better when i started to grow more. Well, at least not i have plenty of night shirts. Having never made it past 5'3'', i came to terms with not being a giant in this life and instead decided i must have been one in a past life.
I then became of my more draconic affiliation, which did go well with the large stature i had associated my self with for some time. So for me the transition of giantkin to dragonkin went rather smoothly. Well, aside from the transition of thinking i was a human to now believing i was a mythical draconic creature that was much less human then i could comprehend.
for me being a giant seemed rather believable at the time. Go figure.
