It is perfectly normal for both the outer labia (labia majora) and inner labia (labia minora) to vary in size color, shape and for one side to be larger or smaller than the other. The medical word for this is called, “normal variation”. There is no perfect size, shape or color that labia should be. It can be upsetting to think you may be different from other girls your age but it is also perfectly normal to be accepting of your body, or not to think about the size of your labia at all. For some girls and women, concerns about how their body looks can become overwhelming, and can start to affect other areas of their life. If you find yourself unable to stop thinking about your body, or if your concerns impact your ability to go to work/school, spend time with family/friends, or do other things you enjoy, it is important that you see your health care provider so you know if you have “normal variation” and you can discuss whether talking to a counselor might be helpful.
