Yep. The other day i finally got around to going out and buying a pair of internally-threaded 2g plugs (the ones that came with the tapers my friend let me borrow were double flares ). Didn't want to risk fucking up my ears so decided to go the safer route. They're acrylic, which isn't as good as glass or metal, but the one time i used metal my ears stank so bad I had to clean them multiple times a day and oh god it was awful. And I've never had a problem with acrylic.
