Is it normal that i love poop and things associated with poop

im 21 years old, and i seem to have a very odd obsession. for one i love to smell my farts, like when i have to fart i will cup my hand over my butthole fart and put my cupped hand to my nose and inhale deeply, sometimes i accidently woft them in public, i cant tell you how many times i have been caught by a car at a stop light wofting my farts to my nose and feel humiliated, sometimes when i poop ill get a plastic bag i'll put it over my hand and actually pick my poop up out of the toilet and squeeze it and make it moosh through my fingers, i often wipe my finger through my buttcrack and smell it. I also fart in my bathtub and catch the escaping bubbles in a jar so i can have pure fart extract. is this normal?
