Is it normal to be aroused by pus?

I've had a really bad habit of biting the skin around my finger nails for as long as I can remember. Usually it just results in a sore or some bleeding, but occasionally they'll get infected, and after a while, will start leaking pus. I've never had a problem with it, in fact, I've always kind of liked licking bloodied or even pus-leaking wounds. But recently I've realized that squeezing the pus out of wounds, licking it up, and even looking at pictures online gets me kind of aroused. I know it's weird, and part of me realizes that it's sort of gross, but I still kind of like it (As a bit of a side note, I've also been really into blood and body horror for quite a while now). Thoughts?
