Get a portapotty. They’ll drop it off in front of your house. Go outside to go. Hose it down once a week. They’ll come and pick it up whenever you dial in. They’re for construction workers, nobody has to know. They’ll think you’ve got a remodel going on, it’s for the workers. Get a portapotty.
Get an outdoor shower. It’s a hose and a shower head. You can get heated tanks no problem. Shower outside, like god intended. Naked in the woods or on your own lawn. Like god intended. “The neighbors will see!” Let them. If you are ashamed of how you look, then hit the weights. Let them look, want them to know what you got going on.
