I'm still occasionally thinking about getting a nipple piercing, though still not very seriously. I don't see it as some sort of fashion statement but instead as it's potential for variation with regard to sexual stimulation. In that vein the idea of spending months in painful recovery makes the idea much less attractive except in those moments of sexual stimulation.
I've also wondered if I should get a ring or a bar. I'm leaning toward bar simply because it poses less risk for getting hooked on things or flipping up and down or rubbing around during recovery. A ring would provide more variety in usage, but to be honest I don't have much desire to have it used in any way a ring would be.
I'm still sticking to not getting one, though the idea persists.
