Bath towel, washglove and dishcloth : every sunday.
Bedsheets : every two weeks (weekly during summer when it's really hot).
I live in a very dry region, so I rarely have to worry about mold as long as I let everything dry properly after use (aka, not in a ball). If something start to smell moldy I bath it in baking soda for a day or two then wash it. All clean.
47W. Never wanted kids. I don't miss it. I'm happy when I see my friends' kids but I really don't want one.
I have time for me and I couldn't afford raising one but again, I've never ever felt the need to be a parent.
No one has ever pressured me into having children. People knew I wasn't the the type even when I was a kid. They never questioned my choice not to get married either. So no peer pressure.
