The
labia minora (singular:
labium minus), also known as the
inner labia,
inner lips,
vaginal lips or
nymphae, are two flaps of skin on either side of the human
vaginal opening, situated between the
labia majora (outer labia, or outer lips). Inner lips vary widely in size, color, and shape from individual to individual. They are homologous to the male
foreskin,
frenulum,
urethra but no other
penile skin.
