I don't know what forum it's in but it's not so long since we all discussed what kind of knickers we wore
I rotate them in my underwear drawer so they all get their turn to be worn. Freshly ironed to the front. Clean pair taken from the back. Easy.
Of course I iron my underwear. They're cotton. I couldn't possibly wear them wrinkled. I iron my partners boxers too. I would be mortified if he had an accident and anyone saw him in unironed pants ::
