So, how can a worried woman tell if her vulva measures up? After all, pornography hardly presents a varied demographic, and staring at other women’s crotches in the locker room is frowned upon at most gyms. But, according to the experts, if all the necessary parts are there — labia majora (outer labia), labia minora (inner labia), clitoris, introitis (vaginal opening) — you’re probably more normal than you think. “There are certain anatomical landmarks that characterize normal genitalia, but there is no definition of what a normal appearance is,” says Dr. Leah Millheiser, assistant clinical professor at Stanford University Medical Center and director of the Female Sexual Medicine Program. “The vulva can come in a variety of colors or hair patterns and labia of different sizes. I’m only concerned if there’s new development of moles or discoloration, which could be an indicator of skin cancer. Beyond that, women generally have nothing to worry about.”
