Is it normal to do this with my calluses?

I play guitar a lot so i have plenty of thick calluses on my thumb and fingers. I also smoke rolled cigarettes so the calluses are all brown and weird. sometimes i like to bite little pieces of my calluses and suck on them because they taste like tobacco. I also like to let my cigarette burn down and heat the calluses because they aren't very sensitive and retain heat well, and then i'll touch them to sensitive parts of my face like my lips or my cheeks. sometimes it's really hot. when i work in restaurants that serve rolls i like to get them fresh out of the oven and put one in my pocket and also hide somewhere and put one on my cheek, and then on the other cheek, of my face of course. i'm not a food pervert or anything, it's totally innocent and stimulating, like a nice blanket or a hug or something. i was just wondering if anybody else does these things or something similar. i guess it's kind of like being comforted by warm, fragrant laundry.
