Even if [insert fantasy escapism genre] is a rape metaphor it’s unlikely to cede to political correctness because one of the most common fantasies for women is safe/pretend rape. It’s easy to find criticisms of trashy dimestore novels or romance literature for portraying stalking and other unhealthy behaviors as misogynistic or problematic but women eat it up. Money talks, BS walks.
I’m absolutely floored at the suggestion that vampire mythos isn’t about sex. Of course it’s about sex. It’s either snatch and bite “legitimate rape” or it’s hypnotize and seduce her against her conscious will or it’s a tortured soul drinking the blood out of the refrigerator in self-abuse, to avoid sullying the body of the maiden.
Even the best subversions of the vampire myth - Darla in the first episode of Buffy, vampire wannabes - are great specifically because they’re still about sex, only they’re extra shocking because the perpetrator isn’t the expected rapist gender or a person’s not supposed to go out looking to be sexed up.
Stoker’s Dracula was sexy as hell, in all the ways that MEN most fear - he was old, rich and ugly. It gives young, poor and handsome men fits of rage to consider that their arm candy can be seduced *or *raped by a guy like that.
But to answer the question in the OP: no, or at least, not yet. Even while we appreciate the sexiness of vampires like Angel, Spike and Glitterboy, part of their appeal is that they hate themselves for what they do and who they are. When Spike *actually * attempts to rape Buffy, the glamour is gone, and she, and he, and we, are completely disgusted. On the balance, the narrative is still that biting/sex/rape is bad, even when it feels good. Might this change sometime in the future? Sure. But the taboo against blood is pretty strong, and I don’t see the metaphor becoming completely inverted any time soon. These stories don’t propagate rape (or sex), they warn against it.
One problem with your question is many of the modern vampire stories remove the element of spirituality and the mostly Christian religious elements from the fiction world reality their vampires live in. In doing this they can often eliminate the really big, negative aspect of someone becoming a vampire (i.e., they lose their soul and are damned to hell, etc.). Once this occurs the act of being a vampire, becoming a vampire or transforming someone into a vampire because more ethically murkier. To be blunt, remove the religious component to vampirism, and being transformed to one because desirable to people who want to have superpowers and longevity? Once the “vampire’s curse” becomes a desirable gift, the rape analogy falls flat.
As someone who has published multiple vampire stories in pro markets, I can confidently say that categorizing vampire stories as all about rape can only come from the crudest knowledge of the subgenre. It’s a glib generalization that just doesn’t hold water if you consider the entire genre (hell, it doesn’t even hold water for Twilight.)
Consider this. (It’s short.) No rape, no seduction, and the vampires involved are clearly in a consensual relationship.
You can’t generalize about vampires. One reason I return to them as a subject is because more than any other monster, their characteristics are vast (and often contradictory) and you can pick and choose which ones fit for the story you want to tell.
