I got my navel pierced 17 years ago when I was 19 and I still have it
I was fairly thin when I got it but it took forever to heal. This was before ultra low rise jeans too, so pants were always rubbing up against it. I took it out when I was pregnant, then put it back in when I was done having kids like 4 years later (which meant pretty much repiercing it- I did it myself because I would have been embarrassed to go get it done at that point). It healed, even though I was very overweight when I put it back in.
