In both sexes, there is a long process of arousal that intensifies progressively. Men's and women's orgasmic contractions occur at pretty much the same rate, at intervals of .8 seconds. Here's where the difference sets in. This time period can last anywhere from a few minutes in younger men to a couple of days in some older guys. The physiological purpose of the refractory period is not entirely clear.
Some researchers think that it's time for the prostate, seminal vesicles, and other ducts to refuel.
But, in actuality, that refueling process takes hours, whereas the refractory period is often much shorter for men. During this refractory period, a man's blood pressure, pulse, and breathing rates gradually return to their pre-arousal levels. The scrotum and testes descend to their normal position. A thin film of perspiration may appear over much of a man's body. Men experience feelings of deep relaxation and tranquillity during this time.
