I woud never classify my self as normal. I have a few learning differences that make it hard to learn in school. i have some weird tendencies and i definetly listen to metal music all the time..
It is ok not to be normal, and fetish is something usually developed when something disrupts your normal development when you are very young and your mind subconsciously attaches to something, you would not even be aware of it happening till much later and then it is with you for life.
@CeoriAvalon It can be something that simple, once read of a guy who became attached to a safety pin, you would just look at one and become memorized and get a warm feeling all over. I understand the feeling I was badly injured around that age and things happened.
