However I really wanted to try the pa5000 and it's plastic rings are too thick a gauge for me. Also, plastic is so easy to break. Where is the security in that? So my trusty dremel and I set about converting a horseshoe ring to fit. I am currently locked in as a trial. So far I've worn it 24 hours. It's extremely comfortable except for nighttime erections that cause the sensitive piercing area a bit of stress. It will be great in a year or two.
If anyone is interested in how to make their own metal pa5000 ring please comment and I will post more on it.
