You go through a roll in a couple days?
In my household with 3 adults, we go through maybe a roll every 2 weeks or so. It's almost exclusively used for number 2 business though, so maybe that accounts for some of that difference.
Or, we just use very different types of paper, and yours require more of it for the same effect. :)
You may suggest whatever you want :) We do have an installed bidet in our main bathroom, as most houses where I live has those. Tried it, didn't like it, will proceed with using paper as currently it doesn't have many drawbacks and doesn't leave me feeling "more dirty" afterwards than using water would.
