IF a drop of semon has more lives than a drop of blood... why doesnt Dracula suck di€k?

There was a book I read about 10 years ago that addressed that. Not so much the lives, but the amount of protein. The author's name was Poppy Z. Brite, and the outcome was that the vampires in the story were gay. Not saying there's anything wrong with that, but I think perhaps that's why certain mainstream authors avoid the subject.
