Once you take your fingers out of your vagina, follow the trail of your genitals a bit lower. Right under your vaginal opening is a flat length . Vulva: When people refer to the "vagina," what they usually mean is the vulva, which includes all the external parts, including the inner and outer lips. Labia Majora/Outer Lips: These are the first things you see, and hair grows on them naturally. When a woman is aroused, the vestibular bulbs, which lie underneath the labia minora (inner lips), swell with blood and become engorged, somewhat like a penis — which only makes sense, because they’re made from the same spongy tissue as the penis.
