In our culture women are taught to think of menstruation only in negative terms - embarrassing, shameful, dirty, gross, smelly, inconvenient - and to ignore the many benefits of menstruation or how menstruation fits in with our wider cycles. Because women don't understand menstruation and feel uncomfortable discussing the subject it means that they are less likely to learn about menstruation in order to learn about benefits or how to manage problems like menstrual cramps.
