"Spirituality often involves looking inward. But it can generate a feeling of connectedness in more ways than you might have imagined. A study in September found that women who rank high on a test for spirituality, particularly connectedness, are more likely to have more sex with more partners. Men who thought of themselves as spiritual were not similarly promiscuous, however."
