Sanguinarian vampires are those that feed on blood otherwise known as blood-feeders or blood-drinkers.
They feel the hunger and the only way to satisfy such hunger is by drinking blood.
The term Sanguinarian roots from a Latin word Sanguinarius which means "blood-thirsty".
The thirst or hunger isn't pretentious as it's felt deep-down their spines and since blood-drinking is such a sensitive matter, practicing such involves a lot of responsibilities and precautions so if you're not a Sanguinarian Vampire, please don't drink blood just for the sake of drinking.
The Sanguinarian vampire is the type of vampire where the popular fiction vampire figures are usually patterned after only to such an extreme extent.
In reality, a Sanguinarius is a person too, one who isn't immortal so if you encounter someone saying that he/she is 600 year old or so, run fast as he/she may be something else other than a real vampire.
In role play and fiction, it's okay to pretend that Vampires are immortal but then again, such a theory is nothing but an exageration of mainstream media.
It's really hard to determine a real Sanguinarian than a lifestyler if the only measure is blood-drinking, anyone who's got the stomach can pretend by drinking blood but the real determinant is the reason for drinking such.
Blood drinking is the thing that makes a vampire sexy that's why too many pretends to be Sanguinarian and if you are one of those people who want to pretend to be a Sanguinarius, please bear in mind the sensitivity and the dangers involved in drinking blood incorrectly.
