" Instead of celebrating our cyclic nature as a positive aspect of our female being, up until very recently we’ve been taught that we shouldn’t acknowledge our periods at all, lest we neglect the needs of our spouses and children. Consider this excerpt from a 1963 insert inside a tampon box: WHEN YOU’RE A WIFE Don’t take advantage of your husband. That’s an old rule of good marriage behavior that’s just as sensible now as it ever was. Of course, you’ll not try to take advantage, but sometimes ways of taking advantage aren’t obvious. You wouldn’t connect it with menstruation, for instance. Yet, if you neglect the simple rules that make menstruation a normal time of month, and retire for a few days each month, as though you were ill, you’re taking advantage of your husband’s good nature. He married a full-time wife, not a part-time one. So you should be active, peppy, and cheerful every day.27 "
