If you talk to piercers, they will tell you that a lot of their trade is doing ‘normal’ piercings. I mean nostrils, ears and so forth. I would hesitate to use the word ‘boring’, or even acceptable.
You can look for more unusual things. You can do a quick search on the Web and find all sorts of extreme piercings, but you don’t have to go that far.
You can find that your piercer is extra enthusiastic about your choice. I had a rhino piercing and my piercer was so thrilled to do it and so pleased with the result, because it’s rare. But it will get you attention, and, if you don’t want that… well, of course you do, that’s why you are having the piercing in the first place.
One of my easiest piercings was the nape of my neck. It entertains people behind me on the bus.
