I'm a little perplexed by the idea of a "fursona" as people describe them. I'm not a furry, I don't identify as one, I'm not necessarily part of the community in any way other than having an FA account where I post artwork or engage in roleplay activities where some of my interests happen to overlap with the furry fandom.
I've always been under the impression that a fursona, as you'd expect from the word itself, is a sort of persona meant to represent a person if they happened to be an anthropomorphic animal. Am I correct in that assumption? And if so, why is it so common to have multiple "fursona"s? At what point is it just an OC? Do people use the words "fursona" and "OC" interchangeably? I'm not trying to be snarky, I'm legitimately a little confused and curious to know.
All that aside, I don't have a "fursona", but I have plenty of characters who are all typically quite different from me as a person- and while I'm asexual, I tend to interpret their respective sexualities as being entirely up in the air unless something presents itself as plausible, or the way the character develops in personality and story seems to lean in a specific direction. I guess in a way, the characters figure it out for themselves and I'm just along for the ride.
