So if Vamps are - undead - cannot have babies, don't have a working circulatory system... How do they get it up? Erections need blood, it pumps from one head to the other (yes, I know it's more complicated than that). Wait for it, I can hear your cogs turning... Don't you dare answer with - "They drink blood!" - Shame on you, I eat steak, does this fuel my rampaging man-thing? Cause it doesn't (well it does but, once again it's complicated).
