My mother said she thought you couldn’t use Tampax until you were married, ie. no longer as pure as virgin snow, but she raised no objection when I started using them quite early on, so I don’t think she really believed it.
OTOH, the mother of my German exchange student (I was 16) wouldn’t allow her daughters to have a bath or wash their hair during their period. Her younger daughter had a major tantrum at the dinner table one night, on account of being unable to wash her hair.
It says something that I still remember some of the exact words, so for anyone who understands German, ‘Ich kann es nicht mehr leiden!’ (I can’t bear it any more!)
followed immediately by, ‘Immer ein Theater!’ (Always a drama!) from Mutti.
I was so grateful that I didn’t have such an old-fashioned mother!
