I like the concept of this but the flat back sinks way too much into my tongue and for the one day I wore it, I was constantly having to push it out and I saw a white ring beginning to form around it. If you're not careful, I think this could imbed easily. And I've had my tongue pierced for 9 years. The length wasn't the issue either, I normally wear a shorter bar, so it wasn't too short. I also think since it's a (metal) dome and not a ball, the edges could interfere with certain things you'd do with a partner and could easily snag on skin. Good idea though, maybe just not for my anatomy?
