Is it normal i like the taste of my own blood?

So a while ago my mom gave me a family heirloom that’s a pocket knife. Being someone who likes flipping things, I’ve made sort of a game out of flipping the knife. As you’d expect, I sometimes cut my hands doing this, but the weird thing is I really enjoy licking the cuts. I mean, it’s not like I’m drinking someone else’s blood, right? Is this normal?
