Does weight affect the size of a womans vulva?

It sure can: Women of all ages & sizes have many different shapes & sizes of labia (vaginal lips)-also called labia majora (outer lips) & labia minora (the inner lips). The labia majora & mons (upper portion over pubic bone/ lower edge of abdomen)- are most affected by weight. The important thing to know is that labia come in all kinds of shapes & sizes. True abnormalities are really rare!
