Are you able to wipe it off? Is it itchy? Any pain or irritation? The yellow stuff you’re referring to is the build up of dead skin cells, oil, and other fluids throughout the day called smegma. Irregular washing or not washing your genitalia well can cause it to build up. It is normal to have some smegma but when left alone it may produce an unpleasant odor and cause itchiness. When showering, it is important that you wash between the folds of your labia and underneath the clitoral hood.
