My name is something I've always kinda liked. Not even sure why really

. I've always used it for rpg characters and stuff, and Luke just sounds like me when I say it out loud. It's a name that's been really easy for me to associate with myself, even though I'm nowhere near completely out. (Sometimes when I play tennis and have a rough set I'll think 'Get it together, Luke!' without even thinking about it.)
Still haven't had a middle name that gives me that giddy feeling like Luke does, so I'm definitely still thinking about it. My birth name is out of the question because it's not even close to unisex. Got a few in mind, but like you I don't want to tell anyone until I'm positive.
For me, the first name came naturally. Just test the names out on yourself (I'm gonna have to try out the Starbucks idea!). Whatever sticks, sticks! Good luck and I hope you figure out something you like.
