While it may be the thing of porn legend and teenage boys’ wet dreams, the idea of a female sex addict is actually rarely considered. Most depictions of people suffering from hypersexuality (if you even want to believe in the concept) are that of men. This is because women are a) perceived as less sexual than men and b) women who are sexual are branded sluts. If a woman does have issues with her sexual relationships, it might be very challenging for her to discuss and get help with them.
Also note the difference between sex, relationship and love addiction.
