Peeing off the back porch is actually a thing many natives do. I lived there in the 90’s and multiple guys I worked with did it every morning.
The civilized thing to do is get up early, stake out the bathroom, and make the girls dance /S
Heck, it’s YOUR house!
I use the outside more than the inside. Heavy screen of trees on 3 sides.
The neighbor’s husky comes over a couple of times a day for a milk bone and always marks my spot.
