My mom said her first choice for my name was Jessica Lynn. Or, if I'd been a boy, Jacob. Thank GOD the former didn't stick XD, and Jacob I dislike. It's my favorite cousin's name, I'm letting him keep his name. XD
My first name, Christopher, is just a more masculine version of my unisex given name. I destroyed all my old journals, so I don't remember how I came to it. It feels right to me. My mom always asks why I don't keep my given name, as it's unisex, but it just makes me gag and doesn't feel like me.
My middle names have changed a lot. XD Originally, it was Louis so I could keep my initials, but that died pretty quickly, since I figured I could still sign my things with "CLB" even if my middle name started with an S (I did flip-flop between Louis and my old obviously female middle name).

Silas replaced Louis I think shortly after, when my friend introduced me by my old name to his uncle, who said he had a brother with my old name and the middle name Silas. Then Ian came in front of Silas... XD when I had to type my given name in computer class a lot... I'd look down, then when I looked up, only "ian.[last name]" showed. I hated it, but I felt like it fit.
I often think about adding names, or exchanging. But I'm actually pleased with it now. ^_^ Christopher, though, was never very hard for me. I liked it, since it reminds me of lions and boldness, hahaa.
Adrian seems really common among FTMs, hahaa. It's my new baby cousin's name as well. :3 It might take a while to get used to the name for you, but if you're comfortable and it sounds right, then I don't think it'll take very long.
