I also have similar concerns with did I leave something out, did it drop between something, or get left in one of the machines. I wear panties most days under drab while working. When I come home from work I change into male underwear and have a spot for dirty panties in my dresser. I wear the male undies to the gym in the morning and toss them into the clothes hamper. My wife works a lot of Saturdays, so I just get up early and throw mine stuff in the wash with a load of other things out of the hamper. I would not just wash my stuff alone it is not enough and a bit of a waste.Hiding it was worse. Omg did i leave something out? Did i leave something in the machine? Did sonething drop while putting it away? Led to several return trips home after leaving bc i was freaking out.
