My advice is to just be yourself.
Being a furry means you enjoy anthropomorphic animals, but you don't need a fursuit to become one, you just need to have a fascination with the fandom.
If you believe you're a furry, then you pretty much are one lol
I'm officially coming out as a furry! Hard to believe that 2 years ago I was furryphobic and I used to raid this place a lot but I've matured a lot and I've admired furries so much recently that I'm now gonna start being one myself!
