While I now have had pierced ears for quite some time, it has not been in a painless saga.
My ears were originally pierced when I was a baby, but an unfortunate episode involving a sweater left a tear in my lobe (I was too small to remember. Or too traumatized?) The rip didn't go all the way through, thank goodness, but I never wore earrings again from that day forward.
My sister is much older than me, and when I was small I did what any self-respecting little sister would do, which is meddle in her possessions. I was messing around with her earrings and found, to my delight, that my holes had not closed up.
I then proceeded to heartlessly shove any sort of earring through the piercings, and it was not soon after when they began to ooze unpleasantly. It turns out my ears are fineshemeker-ish, refusing to tolerate anything other than 14K gold.
Later I got the long tear in my lobe professionally stitched up (it turned out I was totally overcharged for that) and so needed re-piercing. I went to a lady in a house in Brooklyn.
"Titanium," she said, when I told her of the ooze, and she pierced my ears with titanium studs, which worked fabulously. My niece's ears were exuding pus until I gave her a spare pair of titanium studs I purchased inexpensively for such emergencies on Ebay.
Now you know. Piercing ears, just get titanium.
