The female sexual response cycle includes phases of excitement, plateau, orgasm, and recovery.

“So the first phase is excitement. Right. And during that phase, your heart rate goes up, you're breathing a little heavier. There is this sex flush, you can see redness in areas like in the vulva, in the breast, I mean in the nipples. And then you go to... and that can last a variety of different times. You'll also start seeing some lubrication vaginally. Right. And then the plateau response is when that is kind of at its peak, and it kind of stays steady, and then you reach orgasm.”
