But you have to recognize that the ladies use TP for #1 & #2, while
gentlemen only use it for #2. And the frequency of #1 exceeds #2.

Male only dwellings tend to use little TP, and often choose rolls of nice
old tough Scottissue that last 2 - 3 months. When ladies are present, then
fluffy/soft/fragile rolls get consumed about 2 per week/per female.

For those who want to try out a portable battery powered bidet:

It's great for those times when the restroom is out of TP.
