1.) Sanitary Sanity by Boiling Oil
Combines two mods that already exist that would be normally incompatible with each other to well, be compatible. Makes it so Sims will always flush the toilet and wash their hands after using the toilet and the other lets males sit while peeing.
2.) Male Sit While Peeing by Squinge
If for some reason you don’t want Boiling Oil’s Sanitary Sanity, this mod allows males to sit comfortably while peeing.
