ringer's handle is obvious, because of her nip rings (& others too)
She's had her nip rings for 15+ years, and loves them. We started with 14 gauge and she now likes the 10 gauge ones even better.
As noted in other emails, cleanliness is essential. Hot showers helped and use of hydrogen peroxide. She also turned the rings several times during the day. Very sore for one day, tender for a couple of days after that, and slowly graduated to nothing over the remaining 2 months. Regular tit play helped to ease the soreness, but no pulling on the nipples. If you are intending on using the rings for bondage, wait until she says it's ok.
Ringer loves the rings, and has never regretted getting them. As you can see in the pic, she sometimes uses them for attaching charms. She especially enjoys wearing sheer blouses and showing her rings off.
If you really don't like them after a year, you can always take them out and let the holes seal up.
