Is it normal that i'm addicted to the smell of farts?

I have this strange addiction. I absolutely love to smell farts. when i hear someone fart my first thought is to stand next to them and smell their farts, I wish I could just stick my nose in their butthole but the most i will usually do is just stand really close. My dream girl is one who likes to constantly fart and will let me stick my nose between her ass cheeks. When I fart myself I usually just cuff if in my hand and try to smell until it goes away, sometimes when im alone i will grab an empty bottle and pull down my pants and fart into it and then smell it that way. if my dog farts and there is no one around I usually just pick it up and sniff its ass. I have a problem i really love the smell of all types of farts and i have no idea what to do. but is it normal because if it is then i wouldn't feel as bad about myself.
