Labia Majora
Thick, hairy, fleshy lips on the outer rim of the vagina.

Clitoris
The only organ on the body (in either sex) that exists solely for sexual pleasure, the clitoris isn't actually in the vagina. Parting both sets of labia, you'll see a small bump that becomes engorged with blood during sexual activity. It can range in size from the very small (you'll have trouble locating it) to a large nub that becomes rigid during stimulatioon. We recommend locating yours right away.

G-Spot
A small mass of tissue which can range in size from a bb pellet to a large pea. It is located inside the vagina, 1 1/2 - 3 inches from the opening and on the top edge of the vagina if you're standing up.

Urethra
Small opening below the clitoris, but above the lower vaginal opening.
