The friend part of me says "you'd look great with the piercing", but the old man part of me says "you'll regret it later".
From most of the responses thus far, it seems to be a consensus to do the center (if you do it) for general symmetry, though I could see you with one off towards one side, as well - similar to the way eyebrow piercings are way off to the side usually. If it were off to the side, it may remind me of a fish on a hook, whereas, one in the center is just more aesthetic (most people prefer symmetry). Off to the side could indicate more of an off-center personality, someone more unique nd unusual (as if piercings alone didn't convey it well enough).
For someone lacking a tattoo and who has worn his earing about 3 nights in the past 10 yrs, I sure say a lot but don't say much. The only thing I will strongly urge is a) don't listen to the old man part of me, he's a fuddy-duddy and you're too young and exuberant to live by his standards, and b) do what
you think is right - you're the one that has to live with it.
Oooohh, what about using photoshop and a pic of yourself to see what your options may look like after the fact? That way you can decide ahead of time if you want it, where you want it, and what kind of jewelry you'd like to see yourself wearing? (BBB, does this open up a new avenue of gifts for m'lady?

).
