It’s mainly the brain and hormones resetting after ejaculation. Dopamine drops and prolactin rises, which reduces desire and creates a cool down phase so the body can recover and regulate arousal
Or do you think the male body needs a recovery phase after ejaculation?
After ejaculation, most men enter a recovery phase called the refractory period. During this time, sexual arousal drops and it may take minutes, hours, or longer before another orgasm is possible.
Women do not usually experience the same type of recovery period, which is why some can remain sexually responsive and may be capable of multiple orgasms without a long break.
Of course, individual differences exist.
