Quote by BelleduJour
I can't speak for every woman but I have had this sensation on occassion. it only occurres when I am supremely aroused and wearing less constricting bottoms that I am able to experience this sensation. Certainly does not happen all the time.
Of all our inventions for mass communication, 
I am tiny - I guess you could say "trim". In the summer especially, I wear loose short with nothing under them, and I definitely feel the sensation. Some shorts are better for this than others - I have a pair of cheap ones from Kohls - the butt fits fine, the leg openings are loose and the legs are about 3 inches long (so if I want, I can engineer an accidental sighting for someone) and the crotch seam is tight - it rubs directly against my pussy when I walk. I absolutely love these shorts - I am stimulated with each step. Combine that with my small B cup breasts, which are almost always braless under my loose blouses or tshirts - my nipples love the stimulation -- I can get super turned on and just love the feeling of taking a walk at lunchtime.
I have full labia, both inner and outer, but only feel them sliding past each other when I've just had sex and a guy's cum is running out of me. Otherwise, they pretty much stick together when I walk.
Only when I am very aroused and not wearing any kind of pants or shorts. Mostly a Dress or skirt
