Men's beards are also closely related to their abilities (sex knowledge adult novel)

1. The duration of a high-quality sex life is 13 minutes. The latest research from the University of Pennsylvania in the United States shows that people’s expectations for long-term intimacy are actually wrong. A good sex life lasts 13 minutes. More than 20 minutes will make people feel tired, and less than 5 minutes is too hasty. The primary factor in ensuring quality sex time is sleep. If you sleep less than 6 hours a day, you are prone to "sexual fatigue." Spliced ​​sleep time will also reduce your expectations for sex. Instead of sleeping for a total of 10 hours in three times a day, it is better to sleep for 7 hours in one go at night.
2. Men are most eager for sex in the morning and autumn, but men are not always available on demand. Finnish medical experts say that a man's sexual desire is directly proportional to the level of male hormones in his body. The amount of testosterone secreted in the early morning is one and a half times that of noon and 16% higher than that of evening; and autumn is the time when men secrete the most testosterone in the year.
3. The faster a man falls asleep after making love, the healthier he is. Don’t feel disappointed when your boyfriend falls asleep quickly after making love! French sexual medicine researchers say that a man's cerebral cortex and neuromuscular system are in a highly, short-term state of excitement during orgasm, which then quickly subsides as the excitement dissipates, and the neurons enter a period of inhibition, necessitating an urgent need to fall asleep. The faster the neuron inhibition period comes, the stronger the man's body's repair ability. Therefore, the faster a man falls asleep after sex, the better his physical condition is.
4. The faster a man's beard grows, the stronger his sexual needs. A man's beard is also closely related to his sexual ability. The American Journal of Epidemiology states that the faster a man's beard grows, the better his metabolism and the stronger his sexual desire. If you want to test your new boyfriend's character, the most direct way is to observe how often he shaves.
5. Drinking cold drinks after sex can irritate the stomach. Do you often feel thirsty after sex? Don't drink cold drinks at this time! You can drink some warm water. Korean medical experts say that when you are intimate, your gastrointestinal blood vessels are always in a state of expansion and the gastrointestinal mucosa is congested. Drinking cold drinks at this time will irritate the stomach wall and cause stomach cramps or stomach colic.
6. Men are more likely to have sex when they are unhappy
7. The best sex environment temperature is 27 degrees
8 Men change positions just to please women
