cleaning the cauldron makes rags dirty but so does cleaning the room and dusting, dusting knocks dust onto the floor forcing you to sweep an additional time if you did it prior. You should only clean the laundry AFTER all jobs that make them dirty. I usually get 1 extra jug so i can get enough water to do everything that requires water in 1 go without interrupting the process by forcing me to get another refill and wasting more time than needed.
i usually do it in the order of:
1. start fire
2. clean cauldron
3. cut veggies & meat (if going to town for ingredients, instead clean room)
4. cook food (if going to town, instead dust)
5. clean room (if going to town, instead sweep)
6. dust the room (if going to town, instead wash laundry)
6. sweep (if going to town, instead hang laundry and head to town)
7. wash rags & clothes (once returning from town, get started on food if you have more than 1 hour and 50 minutes. otherwise save the ingredients for the next day since you wont have enough time to finish it anyways)
8. go outside and hang the laundry (once food is in process, go out and fold the laundry, then continue the rest of the steps as normal, minus laundry)
9. chop wood & refill water
10. go in to stir stew and wait till laundry is dry then get that done and then spend the rest of time doing what you need.
you can also try to look for dark brown potions which are relaxation potions that allow you to lower horniness without wasting any time compared to spending 30 minutes to masturbate to lower it.
Incidentally, and on a completely unrelated note, I think I've played this a little more than I should've.
