I win!
Seriously though, I started out with a high stem.
As you ride more and more, the bike will force you to conform to it and
you'll become more flexible and use those core muscles that are needed
in cycling (if you already aren't at that level yet).
My suggestion, practice riding with the stem in different positions and see how you like it.
When I look at my bike, I can't believe it's comfortable to me, but it is. Much more so than
my first road bike that had a low seat and high stem. FTR, I'm 5'9" and ride a 56cm.
I'm just picking on you because I'm jealous!

Enjoy it man! I ain't no hater!
I don't know you, but I'm always happy when someone gets a nice rig like that.
