Can I get cut or scratched? Yes you can so make sure you look over your jewelry and notice if there are any breaks or metal that is not smooth. If you marred the jewelry, get rid of it and get new ones.
Does the nipple jewelry, or body ornaments, have enough area to stay put?
Diameter of the jewelry plays an important part. You do not want the gauge of the jewelry to be too small that it will not stay in place, nor too give to be a burden. Unless you like the large thickness look!
What the type that will work for you, either as piercing jewelry or non-piercing or fake jewelry?
Almost all jewelry and other types can be worn as labrets, nose, lip, eyebrow, dermo, and bone jewelry. These can be worn even in the ears in place of standard earrings. Yet, not all jewelry can be worn just anywhere.
