It's your right to do whatever you like with your body, and it's no business of anybody else but yourself. If you like body art and piercings then it's down to you. There are many kinds of prejudice in this world, and I'm afraid this is just another example of the way some people think we should all fall in with what they class as normal.
Now having said that I have to admit that as I have got older I have grown to like my own tattoos less and less and have even got to a point where I have thought about having a couple of them removed. There again that is not because of what anybody has said to me. In fact I don't think anybody has mentioned them to me for years now, but it's simply because I think they are not me anymore.
