An interesting (and surprising for me) fact transpired from an innocent and unrelated discussion about cats: some people change their bed linen weekly. How often do you change yours?
Is it related to how often you / your partner have a shower? How often do you wash?
I have 2 showers a day, husband - 1, and I don't change bedlinen more often than every 2-3 weeks.
[I don't know if it's strictly speaking AIBU, rather than "are we being dirty-cunted?" Please, dears, let's be respectful towards each other in this sensitive subject ;)]
