Why men lose sexual desire after ejaculation?

Men weren’t designed to have continuous sex but to impregnate their wives. A typical male will lose sexual desire for some time after orgasm. This is called the refractory period.

According to Wikipedia, the hormone oxytocin, which is produced right after ejaculation, is believed to be the main reason why men lose their sexual desire after it.

The release of prolactin, which is a chemical that suppresses the release of dopamine, is also believed to be among the reasons why men lose their sexual desire after ejaculation. Dopamine fuels sexual desire.

According to some studies, 400% more Oxytocin is produced after a male has real sex than masturbation.

According to one theory, the negative feedback sent from the male sexual organ after ejaculation suppresses sexual desire for some time. (See The body language signs of stress)

The refractory period depends on many factors, including age. According to some studies, the refractory period for 18-year-old males is 15 minutes, while for 70-year-olds, it’s 20 hours.

According to some studies, the average refractory period for most males is 30 minutes. (See The negative psychological effects of masturbation)

The coolidge effect is a phenomenon seen in male mammals where they experience renewed sexual interest if a new female is introduced after losing interest in the first female due to ejaculation.
