so i'm pretty sure i'm piercing my brow, but I was wondering if it really matters which side I get it on?
Which side you get pierced is not that important. You can do it on any side. You can have wide selection jewelry options.
It doesn't really matter, but there are still some assholes who consider the right eyebrow to be the 'gay' eyebrow.
Hmm...I've never heard of the "gay" eyebrow. lol If I was considering getting an eyebrow piercing, I think I'd go with the left. I have no idea. I tend to favor that side for piercings for some reason.
