RE: Vags
Genital area is very sensitive to the point the right stimulation, even if visual, can trigger (heh) a reaction. It's more obvious in men (erections), but it also happens in woman. There are 4e stages of human sexual reaction, and all affect other organs. Just for the curious, this is the process for women (if you wonder, it's less complex for men.)
1. Vaginal lubrication begins. The
vagina expands and lengthens. The outer lips, inner lips, clitoris and sometimes
breasts begin to swell.
Both: Heart rate,
blood pressure and
breathing are all accelerated.
2. The vaginal lips become puffier. The tissues of the walls of the outer third of the
vagina swell with
blood, and the opening to the vagina narrows. The clitoris disappears into its hood. The inner labia (lips) change color (although it's a bit hard to notice).
Both: Breathing and pulse rates quicken. A "sex
flush" may appear on the stomach, chest, shoulders, neck or face. Muscles tense in the thighs, hips, hands and buttocks, and spasms may begin.
3. (Orgasm phase) The first third of the vaginal walls contract rhythmically every eight-tenths of a second. (The number and intensity of the contractions vary depending on the individual orgasm.) The muscles of the uterus also contract barely noticeably.
Both: Breathing, pulse rate and blood pressure continue to rise. Muscle tension and blood-vessel engorgement reach a peak. Sometimes orgasm comes with a grasping-type muscular reflex of the hands and
feet
4. The uterus and clitoris return to their normal positions. Some women may be able to respond to additional stimulation with additional orgasms.
Both: Swelling recedes, any sex flush disappears, and there is a general relaxation of muscle tension.
During sex, pretty much the whole body is working. And the vagina has its own tasks like thickening and contraction. What they've done to Jazz is not only a botched work, but technically, it's fraud. His "vagina" should be doing all of this and it won't. You don't give a patient a new heart and say "btw, it doesn't really work, it's just for you to look like you have a heart". If these surgeries were remotely life-saving then they would do the whole deal.
Because, seriously, what's the point of becoming a woman and having the surgery that gives you the organs that identify your sex if such organs won't allow you to enjoy the activity they're supposed to perform? If these patients were given, I dunno, bionic vaginas that actually move, yeah, I'd could accept it. but they don't.
