I have 4 tattoos and the left side of my nose pierced (along with 4 holes in my ears-3 left, 1 right).
I had my naval done about 10 years ago-before it was so "trendy". Once every 16 year old girl in town started getting one along with every mainstream pop starlet-I took mine out.
I always had trouble with my naval though-so I was glad. It never healed fully-and it was always painful. No matter what I did, my body just wanted to reject it.
I could never get my nipples done, or a VCH done...if my body rejected a naval (and I did have some trouble before my nose finally healed as well) then I don't even want to go there! Plus..I breastfeed my children, so I don't want anything in that area, either, that could possibly affect that.
What I *do* want is more tattoos though...they are my personal preference, if they are done well, and are meaninful to the wearer. (as in, no "generic" tattoos that 500,000 people already have-like guys with a tribal arm band or a Looney Toons Tasmanian Devil.)
I love my nose piercing though...
