I did not go with what my parents would've picked which would've been Kyle. However, they didn't even go with what they picked out for a girl (Lauren) because my named ended up being Kelly.
Since my birth name is unisex, I'm moving it to my middle name (which currently isn't unisex). I would keep it as my first name because it's easy and cheap, but both my parents and me associate it with my femininity, thus, I'm going with Kayden...
which has nothing do with anything in real life. When I was in 8th grade my best friend and I made "muses". Kayden was the very first one I made. He was basically the person I wished I was. I've always secretly identified with it and when I came out as trans that same friend (who was my roommate at the time) immediately suggested I use that as my name until I could think of something else. However, I didn't want to, so thus it stays.
And on that note, yes, Kayden is a real name. Some people think it's completely made up, but no. It exists. A more common spelling is Caden, but this way I will still have the same three initials, which makes my university life easier.
