Some information Mina left out that may or may not be included in the links she provided…..

Blood is a natural emetic, meaning it induces vomiting. The amount your body will allow you to consume must be built up gradually, if at all. I believe I read somewhere that iron poisoning was possible from consuming too much of it. One last "fun fact" about blood before I lose interest in promoting safety…..consuming blood incompatible with yours may kill you.

Yes Alex, there are people whose thirst is satiated through animal blood….such as from rare steak. Clearly this is not their preferred method but it is useful if they have no regular "donor" if you will, or are approaching their donor’s limit for bloodloss. I’d rather not drink animal blood myself. if that was my only option however, I most likely would. but as you said yourself, the fact that the blood is from a human, particularly one I care about, makes it all the more enjoyable. Tasting the blood directly from her is ideal, but I can’t tear up her flesh all the time to keep up with my cravings, making the syringe quite useful.

Love,
Satan
