I don't get this fascination with "vampire" and "werewolves". Stupidest shit, only trailing stupid tattoos in gayness.
Well the vampires, Hollywood has sexualized them, thanks in part to the Ann Rice books. You know, supposedly undead pasty skinned Blood suking men who are asexual, have now become undead pasty skinned blood sucking men who can now hace such sexual charisma that they can think the panties off of a woman, in fact they can have any woman they want.
As far as the werewolves, they represent the wildness of nature and man, plus there is a slight beastiality hint to it. If you ever see some red riding hood comix, the wolf is screwing lil red riding hood
plus there is small subculture called Furries ( look it up) that idolize humanoid animals
