I'm into blood
I've only gotten to play with it after knives and/or needles were used on me (sterilized of course) and I find the idea of playing with blood and/or tasting it from a deep bite mark or scratches I've made with my nails appealing. I wouldn't actually do either of the latter two, because of hygiene issues in regards to how dirty the human mouth is. I only want fresh blood please, no red wings and nothing clotted/old. Ew
I suppose liking knives and needles used on my skin is probably odd to the majority of people on here too >_> But I do believe that my love of blood is more oddball to folks than liking sharp metal things
