Is it normal i like to fart on random surface's?

I like to fart on random places. sometimes the walls/corners of walls, doors, the very corner of cabinet's, any hard surfaces. My farts are usually dry, not a single wet fart in sight. When I fart on these surfaces, the sound echos and feels rough almost hurting my ass.

But I can't stop, it's becoming a habit and if I am not farting on surfaces, i clench my cheeks together as tight as I can; and pass gas. The tighter, the louder. I don't do this in public, and i don't fart on kitchen surfaces/items either. Anything kitchen - related' i won't fart on. Just other things that are not where people are supposed to eat.

The question is though, is it normal?
