I remember when my mother taught me about my menstrual cycle and pregnancy. She, like millions of other mothers before and since, did not have the words or the experience to teach me about the miraculous cycle in my body - the cycle that is responsible for all human life on our planet and connects us to the moon and the tides. Nor did she have the words to teach me about the gift of sensual pleasure that is the birthright of all girls. If she had, my life surely would have been different. For one, I probably would not have suffered from devastating menstrual cramps for decades.
