I can understand the desire to actually leave a mark. Much of the si I do doesn't leave marks, it is just a way to get through the moment and once the moment is gone I don't need the reminder. There are some times however when things get a bit more intense. Those are the times that I do leave marking and find that just looking at the mark is enough to calm me down.
