Who cares? It's your body. If you want it, get it. I've never looked at someone's ears and said "Wow, two piercings? Totally undateable" hahaa. If you want to do it, do it. It's the confidence that matters.
well seeing as though everyone has earrings I wouldn't worry about it. Personally I wear captive bead hoops. Just make sure they're a good grade of metal if you aren't planning on changing them out often.
