Is it normal to poop outdoors all of the time?

I hate pooping inside, it freaks me out... For the last 6 years I have been pooping outside. At first I would go to this field a half mile from my house. But, as I started pooping more often (4-5 times) a day, it became very inconvenient to walk down to the field. As a solution I began pooping in my backyard, when my mom saw all the shit in the yard she was pissed and grounded me. Now, I lay my loads in the neighbors yard. I have heard him yelling when he finds it, but he doesn't know its me!
