Sheets are every other day. The thought of sleeping on all the dead skin cells, dust mits, dander, hair, sweat, dirt and oil is just too much for me. *shudder* I shower every night before bed and I still can't manage more than 2 nights on the same sheets. I do regular laundry on one day and the next day I do the sheets for all 5 beds (mine/dh's and the 4 girls). I always have some form of laundry to do each day. As for towels they are used twice and then washed on bed linen days. We all shower daily. As for when dh and I are intimate...we put something down on the sheets so that it will not soil them. I have a couple crib size mattress pads folded by the bed but if we are at a hotel them we use a couple towels. I not longer have a period because I had a hysterectomy a few years ago but before I would sleep on a crib size mattress pad to make sure if there were any accidents it did not get on the sheets. Comforters/mattress pads/pillows are washed/sanitized every Saturday.
