I don't consider myself a therian/alterhuman but I do relate to this community so much.
All my life I have been fascinated with animals while lacking interest in human beings. In my childhood I used to drew only animals and play with only animal figurines. I also enjoyed monsters and cars (thanks to the movie of the same name) - basically everything non-human.
When I was 6-10 y.o. I was a big dog fan and wanted to have a dog so bad. Also I LOVED miming dogs. I have learnt how to bark (I still can) and ran around on all fours.
Once I said in presence of the whole family that I would like to have claws and fangs if such genetic modification existed. And then dad said to me in a condescending tone "What for, are you a dog???" I still feel bitter honestly, I still do think that claws and fangs would look really aesthetic on me.
Around when I was 10 orthodontic problems occured - I had what's called "dystopic canines". I LOVED them. The thought of being ashamed of my sharky smile never even crossed my mind. When other people/doctors assumed I wanted orthodontic treatment in aesthetic purpose, I was even surprised at first - never before thought others may find such look ugly/uncomfortable etc.
A dentist: Do you want to have such beautiful smile? *points at a model on an advertisement*
Me: Nah, my smile is way better but I'm here only bc it's uncomfortable to eat with a gap under my slay fangs.
But I started wearing braces only around 16 y.o so I had time to enjoy my vampire fangs and for them to be immortalized on multiple photos. Still miss that look(
I love the look and smell of raw meat and may only dream to eat it like that. I also love the smell from fish shops.
I enjoy doing quads but sadly do it so seldom bc 1) knee trauma 2) no safe space. It's a good exercise for me and my back loves it + it trains arms.
I have no therian gear but honestly would like to dress like that! I find it hella aesthetic.
Also I'm way more comfortable being around animals and bonding with them on a deep level rather than with humans. Also I find it difficult to express affection in human ways - animal affection feels way more sincere and satisfying.
But I honestly do not view myself as an animal in human body/non-human. I feel it on a furry level, hehe. I love to portray myself as an animal/creature being and find those versions of me more aesthetic/beautiful than my human body, but won't call that my identity.
P.S. I'm something close to otherhearted probably?
