Is it normal i like to smell myself before i take a shower or bath?

It started when I was real young actually and when I discovered it felt good to touch myself and related it to being naughty. I was around 7 when I started touching my private places at home in my room. And if I was alone I would play with myself like in the livingroom sitting in a chair or on the floor. I'd get naked and touch my pussy and bottom and smell my fingers and sometimes get a hand mirror and look at myself pretending some of my classmates were looking at me and smelling me. My mom got on to me periodically because she would find a wash cloth or a towel in my room that was stained and stinky that I'd sit on and wipe off with as I played. Sometimes I'd use it all week so it would get rather dirty. It was always before I took a bath because I wanted to be stinky with my all day odors so to speak. I let a boy in school smell me when I was 8 and also girls too. Three of my female classmates and I would drape a blanket over our desks at nap time and we would take our pants or shorts off and then pull our panties to the side and look at each other and smell each other. Sometimes we'd wear little skirts or dresses. And it was easy to smell each other's butthole that way. It was fun being nasty like that. We would talk about boys and even our teacher mrs Vanderspeck about smelling her butt too.
