Marquette,
I also think that Vampire erotica is NOT snuff. Whatever killings that happen in your stories are part of the plot and are NOT murders for sexual excitement. In the movies today there are many cold blooded murders depicted including rapes and murders, but they are not called snuff. In my understanding the idea of snuff is when there is no real plot, but only depiction of torture and murder for sexual excitement. I hope I am making sense, 'cause it's a very hard topic to describe and categorize. As far as I am concerned, there is nothing erotic about cold blooded murder. Sexual or not murder is still a murder to me.
