I have left mine in for the whole of my first 2 pgs & doubt I will take it out this time either. I took it out now & then towards the very end depending on what I was wearing as it would get cought on things now & then from sticking out so far LOL.
I don't think my hole will ever close. I can see that it has moved lower then what it was to start with but it still looks normal. Just lucky I guess.
