I'm a guy that really apprecaites neat, tidy, orderly things I suppose. So left on my own, I think I used to wash my towel after using it 3-4 times at the most.

Also, what do you do with the towel once it's too dirty to dry off with? I move it to the floor in front of the shower stall. The one that was already on the floor goes to the hamper, and a fresh towel goes on the rack.

I can't be the only one that follows this rotation, but shion prefers specific towels for the floor.
