Throughout my years of working with women, there is a conversation that I have over and over. The specific details vary, but the bottom line is that an enormous number of women have lost their desire for physical intimacy. We are too tired, too busy, too angry at our partners—at the end of the day, the last thing we want is to let someone into our bodies. For many women, sex has become another thing on the To Do List—an obligation, a favor. What is most surprising and disheartening about this pervasive attitude is the idea that sex is not important for women. Culturally, we give our brothers permission to want sex, to claim its importance, but we don’t do the same for our sisters.
