Is it normal that i like to smell my own ass?

1 time my 9 year old niece was staying with me for 2 nights when my brother and his wife went our if town for the weekend and I caught her with her finger in her butt and she said that it itched and she was seeing what was wrong. And then she took it out of her butt and I smelled her finger and it smelled like a dirty butt, and then I took her to the restroom and I got a wipe and she took her panties off and bent over as soon as she was bent over the smell of ass went in the air and came to my nose and I wiped her butt and she spread her butt open and then I saw her butthole and I wiped her butthole so it would stop itching

Yuck

Hey, is this Jodi Arias?

I always do this, I don't like my vagina to much. I love putting my finger in my butt and sniffing it my butt smell turns me on. I remember my little 8 year brother was sitting looking at cartoons and I pulled down my panties and showed him my butt and I scratched my butt and I put my finger under his nose to smell it and he said "your hands smells like butt" and I was laughing and I bent over and spread my buttcheeks and I let him see my butthole and he said " why are doing this it stinks" I loved doing it for some reason. I love the smell of my butt when it gets sweaty and it has a sweet smell to it im not talking about poop it smells like a dirty butt.

Just don't pick your nose.
