You may have the illusion that having sex is purely a lower body movement, but in fact, the brain is the most important sexual organ! Why do we have sex? Because making love brings wonderful peak pleasure and beautiful and unique intimate experience, which is caused by thousands of complex changes in neurons, transmitters and receptors, Neural pathway in the brain.
Making love activates our 'rewards'
In circuit sex, dopamine, a Neurochemistry substance in the brain, plays a very important role. Dopamine can activate the 'reward circuit' in the brain, allowing us to experience a sense of happiness and pleasure.
Basically, things that activate the reward circuit are either beneficial for your own survival or for the reproduction of genes, such as sex, food, adventure, achieving goals... Food is the best example. The reward circuit believes that 'heat is survival'. High calorie food will make the brain secrete and release a lot of dopamine, producing a sense of pleasure, so we prefer Chocolate cake to water boiled dishes - of course, this is our instinctive response. Some health experts must think that water boiled dishes are more delicious, because of their strong sense and will.
In fact, what we desire is not Chocolate cake, but dopamine. Dopamine is the ultimate driving force behind many of our behaviors.
During Orgasm, dopamine will burst out in large quantities, making us enter a dreamy sensory experience. A Dutch scientist scanned the brain state of people during Orgasm and found that the brain state during orgasm was very similar to that after taking Hallucinogen.
The 'refractory period' after sexual intercourse
After Orgasm, dopamine begins to decrease sharply, and Prolactin is released. If dopamine is the accelerator of sex, then Prolactin is the brake. Prolactin can reduce sexual desire.
The decrease of dopamine and the increase of Prolactin make us enter the "refractory period". Our sexual interest is not so strong. We put aside sex and began to do something else, such as hunting, picking wild fruits, taking children, going to work, cleaning up the home, etc. - otherwise, we would have sex endlessly and could not get up all day. In animal experiments, this effect lasted for about 2 weeks.
The undue period is broken by the "Coolidge effect"
"Coolidge effect" comes from a classic story. President Calvin of the United States. Coolidge and his wife visited a poultry farm and found that there were very few roosters there. The farmer explained that each rooster had to perform its duties dozens of times a day. The First Lady said, "Please tell Mr. President." The President asked, "So, every time a rooster serves the same hen?" "No." The farmer replied, "There are many different hens." The President replied, "Please tell Mrs. Coolidge
