I have other forms of OCD which is why I am asking. I don't have any other contamination OCD. This makes me wonder if it's just a personal dislike. I have always had it since I was a child. I'm not aware that my body is 'dirty' when I have ink on them, it's just something I hate. I don't like the parts of my hands covered in ink touching food though so I must be worried about chemical contamination. Thanks for the reply.
