Strange Bathroom Habits?

Please don't judge but I have very strange bathroom habits. I've already asked this but I need more answers. For Example, I feel I have to squat like a dog over the toilet. Sometimes I even feel I have to go outside at night. Basically It's like a animal's bathroom habits. I never feel comfortable going just sitting and I don't know why. The weirdest one is I sometimes go in the shower, get on all fours, circle a few times, squat, scratch the ground a few times, and go. And this one is very embarring, once in a while I actually do the shower thing, except on the floor. Of course I clean up after wards and I only do it on tile. Oh, and if i'm outside in the woods i'll do the same shower thing and then mark several trees.One more thing, I also enjoy the feel of desperation until I can't hold it anymore. By the way i am a girl. Can anybody explain this?
