Choice of style but some idiot just like many others before them decided that if you get you right ear peirced only then you are Gay.
Nothing it's just a preference and a style. The only piercing that supposedly has meaning is the lobes for guys I believe.
Nothing for me, I have my top right done just because I wanted it done. Same as I just wanted my lobes done.
i have the top of my left ear pierced, and it doesnt really mean anything:) looks pretty though.
some people say if you pierece your right ear that shows that you are gay
