I have wondered if it is such a good idea to incorporate more graphic nature in fiction. I would much rather have a mature audience so my WIP has been quite graphic. Not in subject matter (such as rape, sexual abuse etc.) but the characters' dialogue and small things that add to the plot. To me, it adds some kind of dread like "I would not want to be near that person" or perhaps even a realness to the story. The problem is that I don't want it to seem repetitive or annoying/pointless in any way. There is a character in my story that is always speaking graphically and it is just his way of talking but it has nothing to do with the progression of the plot. If anything it is a progression to his character though. Is there a proper and improper way to do this? Anything in particular?
