Sexual function in women: what is normal?

Sexual function in women has often been measured by clinicians using parameters which appear easier to assess (frequency and pain). Therefore, the range of normality is often broad and of limited value when investigating population groups. The most important features to explore are satisfaction and/or distress with sexual activity. Although female sexual activity decreases with age, dissatisfaction also declines, and rates of female sexual dysfunction may not change significantly. There are cultural differences in sexual behaviour across the world, but overall a satisfying sexual life is important for women's quality of life.
