Why do inner lips hang out?

The inner lips, or labia minora, can vary in size and shape among individuals due to genetic factors, hormonal influences, and anatomical differences. Factors such as age, hormonal changes, and childbirth can also affect their appearance. Some individuals may naturally have more prominent labia, while others may have them tucked in. Ultimately, the diversity in labial appearance is normal and reflects the wide range of human anatomy.
