My wife has not been completely supportive, as to a lot of things. And to be honest there are a lot of things, that she is still not coping with at all well. But she has always been one for being yourself and trying to be the person that makes you happy, so shes caught in a confused place, so I don't push it.
We both got our bellies pierced at the same time, which made it easier for her. And its something that we both have always wanted. But do remember, its something for you and you don't need to show it off. I do from time to time, and have a couple purple barbells in the 2 at my belly. Its something that I enjoy having and I am not prepared to care about anyone else. And when I get my pouch of a belly back under control, I will go about showing it off again, but not until then. That is the fun of those piercings. You can hide it if you want. I love mine, although I do love the nipples more. But thats just me 😛
