Seriously. Like, next time you need to shower, and you also really have to go #1, just wear your undies into the shower. Pull the curtain closed and just let loose. Then turn the water on and stand under the showerhead until you’ve washed your undergarment (and your shower) clean (might have to detach your showerhead). Ring them out, plop them on the toilet lid, and continue your shower like normal. When they’re hung and dried, throw your undies in with the dirty clothes like normal.
Why? Because you’re an adult, it’s warm, and because you can. It’s fun to do random stupid harmless shit like that sometimes, and it can relieve a tiny smidgen of quarantine boredom.
Caution though: not sure if this stains. I’m not too concerned because no one sees my underpants but me/my significant other so yeah.
