About my fursona? Not the first person, no.
First person I told was my best friend, whose like a brother to me. I was already in by he middle of coming out as pansexual to him, so I figured "what the hell".
Second person was a girl I had a crush on, she actually surprisingly knew what furries are, and had asked what mine was. And then went on to see what I thought herself could've been if she was a furry.
And those are the only two people to really be told.
