Is it normal that i do this with my dog?

Hello, my name is Benjamin. My skype is thepurpleben if you have any questions. I have had this hobby since I was thriteen, I'm currently seventeen. I like my dog, it's a brown poodle named Dusty, and I kind of like her. One day I got bored playing games with my friends, and I decided to take a break to "go to the bathroom" as I said to my friends, and that was not what I was doing. I had lay down, place doritos on my chest and call my dog over, to have her lick them off. Sometimes I like to put peanut butter on my stomach for her as well. I'm a little chubby but not fat if you wanted to know that. I still do it to this day, and I even eat the dorito crumbs. Is it normal?
