I love all of a woman’s body. Everything about a woman’s body is fine art. Favorite parts (other than the obvious ones) are behind the knees, small of the back, armpits (must be shaved!) inside of elbows and wrists. And all points above, below, to the left and to the right! They ARE the fairer sex!
Since the forum is "genitalia," and the thread title specifies "a woman' body," the range of answers should be fairly narrow, and limited to the mid-section of a woman's body. I'm going to have to go with Bartholin's glands (also known as greater vestibular glands). Each woman has two of them, and they're compound alveolar glands. The human sexual experience would be far less enjoyable, for both men and women, if women didn't have them. There certainly would be far fewer than 7 billion of us on this planet now if women didn't have them. Our species may not have survived this long at all without the pleasurable coital contact that the lubrication released by these glands makes possible. Most of what I see already posted above isn't genitalia at all, nor unique to women.
My wife is very sensitive behind her knees. Light kisses followed by nibbles makes her gasp and jerk. Always part of foreplay. Along with the rest of her body. So many wonderful parts to be loved, cherished, and taken advantage of.
Genitalia specific, that's a tough one. But I'll have to go with the labia minora. The bigger they are, the more I'm attracted to them. Love giving them a great oral massage and making her squirt. I don't even have to touch her clit.
I love big, fleshy, plump pussy-lips with a deep deep crevice between them. Just the sight of a pussy like that is compellingly bonergenic. And to get my tongue all the way into that crevice — that’s heaven on earth.
I love the female form. From the perspective of strictly beauty, I love the whole shape of a woman. For sexual attraction, I am greatly turned on by labia (of all sizes) and areola. Something about seeing a woman's intimate areas, seeing what her labia look like, the size and color of her areolas, the parts she keeps hidden from the world. Just exhilarating to me.
