Lilylilo I'm with you, slept nude since my late teens (apart from in Hospital)
I change my bedding about every 2 weeks & shower at night so I'm clean when I get into bed (no night sweats)
Towels when needed, kitchen towel when a wash goes on, tea towel same as I rarely dry up 
I have no washing line at the moment & have to rely on washer/dryer so use only when I have a load (watching the "smart meter" showing how much electricity I'm using !!!!!) - I'm concerned at use of resources & cost to me.
I live on my own now & have no spare room so my habits have changed from when DH was alive & we had larger properties
