In the excitatory phase, the tension was above the baseline level of unexcitatory, and there was a significant increase relative to the baseline threshold. When entering the duration period, sexual tension will continue to stabilize at a high level of unevenness, and with the existence of effective stimuli, it can further strengthen and increase the excitement degree of sexual tension. When the height of excitement reaches the threshold of orgasm, it can trigger the emergence of orgasm, which is the end of the duration and the high tide period. At this time, the height of sexual tension and sexual excitement has reached its peak. The diameter of male glans crown increased slightly during the duration. The glans become darker, the testicle becomes larger due to vasocongestion, and the testicle is further elevated to engage in pubic contact.

4. Regression period
This period varies greatly between men and women.
