After sex, men typically are lethargic and completely relaxed, and immediately roll over and going to sleep and they become unresponsive to sexual stimulation and can’t get into another excitement phase until some period of time has elapsed. This recovery time is called refractory period.
But no research has found that women have refractory period after female orgasm. Why is it? The answer is easy women never get a real female orgasm, they get a fake orgasm. Those women who claim that they can get multiple orgasms during one session are all deceived by themselves. They even don’t know what exactly the orgasm is.
According to my research, women also have refractory period after a real female orgasm, and they can’t get into another excitement phase right after orgasm, and become unresponsive to sex and very tired and find it easy to sleep. Multiple orgasms are impossible in women at all. Mechanism is unclear right now. I guess that because female brain also can release some hormones during orgasm that lead to sleepiness and relaxation.
