I have had my nose piercing for about 3 months al least by now I'm not sure and a have a 16 gauge bio-flex labret in with a very small gem. This gem feels like its going backwords and in the nose my piercing is also kind of crooked opps :P... I might get a corkscrew and it seems like its to put in easy from YouTube,but is it hard to take out/put in? Should I get a larger gauge? Will it go backwords too?is the corkscrew better? Or is any other kind better. (im getting the ring on the weekend)

I recommend the corkscrew. Make sure it is surgical grade steel.

Is it hard to put in?

The first few times it's a little fiddly but you get used to it and it's a lot more comfortable to wear and won't come out easily.

Its OK I had to take it out later on :)
