Only my left ear is pierced. I got it done just before I turned 22.

Haha, I disagree with the guys. I think it'd look super cool. If I hadn't gotten my ears pierced as a kid, I probably would've done what you're thinking of doing. The slanted bob haircut sounds like it'd look nice with the earring, but if you're doing to cover the earring up, make sure it's a haircut that fits your face shape so you don't end up regretting it.
Just because it's something new doesn't mean you *shouldn't* do it; if you think you'd like it, go for it :-)) Best of luck!
