Names have been an interesting matter for me. Since I was young I always wanted to go by a different names, Aladdin being an example haha.
I tried going by my middle name, which I like, but it just didn't fit me. I have always loved the name Jonas, but I figured people wouldn't call me something that was as masculine as that if I didn't really present that way completely yet. So, I chose AJ, A from the initial of my first name and J from Jonas. People usually assume my middle name starts with a J, but it starts with a C. Then people start asking why AJ. I usually just say it's because it's a unisex name, which is a reason why I chose it.
However, when I finally do legally change my name, whenever that may be (hopefully in the near-ish future), I will either go with Adrian or Jaye as a first name, I believe. I like Adrian because it's still unisex and it starts with the same letter as my current legal first name. I like Jaye because it's unisex as well and it resembles AJ, but is just simpler. I think I'll keep my middle name because it's unisex and I actually dolike it.
So that will make it either ACS or JCS.
