Every year on September 16, millions of people around the world celebrate their birthdays, making it the day with the largest number of birthdays in the world. This also shows that winter is the peak period for pregnancy. According to the American emerging media "Daily Fun News Network", there are many interesting patterns in human sex, which are as accurate as a calendar.

December is the peak pregnancy period every year, and August is the "low" period for pregnancy throughout the year. Research from the University of Texas believes that "from a biological point of view, the reason is that sperm quality is not high in summer, and long days and short nights can affect ovarian function; while December has many holidays and cold weather, and people tend to have more intense sex, making it easier to get pregnant."

The most people have sex on Fridays, and Monday is the time when sexual activity is low. The data comes from Tokyo Fun's 2011 sex survey. The survey covered the time period, location, frequency of sexual life of men and women in Tokyo, as well as the identity of their sexual partners. It was found that 56% of people would have sex on Friday, followed by Saturday at 30%, followed by Thursday, Wednesday, Sunday, Tuesday and Monday.

83% of people like to make love on rainy or cloudy days. A large-scale survey conducted by a condom company in the United States shows that people are more likely to have a desire for intimacy on rainy days, and their feelings for each other will become closer.

Some people refuse to be intimate because the weather is hot, and some people don't want to be intimate because of the cold. The former is twice as likely as the latter. A survey in the United States found that 35% of people have repeatedly refused to be intimate because of the hot weather, while 19% of people have refused to be intimate because of the cold weather.

The odds of making out in the evening are 13 times higher than in the afternoon. The people surveyed said that sexual intercourse requires the right time and place. Although sexual desire is high in the afternoon, it is not suitable for sex. After finishing the day's work, it is more suitable for sex in the evening.

The frequency of sex will increase after the job becomes stable. Researchers at the University of Lugano in Switzerland found that job instability can lead to low sexual desire, and that sex will be more harmonious for a period of time after the job enters a stable period.

Perfect sex starts with choosing the right time

From 19:00 to 21:00 in the evening, you are full of energy; from 21:00 to 23:00, it is suitable for quick sex

Some people live like "owls" and become more "sexual" as the night goes deeper; some people are "larks" and their sexual activity increases greatly in the early morning. For most men and women, choosing the right time to have sex is very important to get a good sexual experience.

The "2009 American Sex Survey Report" pointed out that there is a time difference between men and women's sexual desire, and the highest point of sexual desire of both parties will coincide in the early morning; at noon, there will be the second "small climax" of each day. "This is because the hormone levels of men and women are at their peak for the day around six or seven in the morning." Yang Dazhong, an attending physician at the Department of Sexual Medicine at Tsinghua University Yuquan Hospital, said. Although early morning is the ideal time for sex, considering sleeping in, working and other issues, there is no time to express the surging passion. At noon, most people are busy with work and have no conditions for love.

Research shows that nighttime is the preferred time for sex. However, the sexual process and feelings will be different in different time periods, and couples should make choices based on each other's "sexual interests."

From 19:00 to 21:00 in the evening, it is the prime time for night activities and also the "good time" for sex. At this time, both parties have clear thoughts, and after a short rest, they have sufficient physical strength, which is most suitable for a lingering and pathos "sex feast". Both husband and wife can get satisfaction from complete and sufficient foreplay and postplay.

From 17:00 to 19:00 in the afternoon, the expressive ability is the strongest, and the ears are most receptive and satisfied with sweet words. If you feel emotionally disconnected from your partner, take advantage of this period. When you get home from get off work, don't be busy eating. Instead, hold your partner in your arms, tell your thoughts in his/her ear, kiss passionately, and let the passion burn.

From 21:00 to 23:00 in the evening, most people prepare to go to bed. And the later the time, the stronger the feeling of fatigue. This time is suitable for quick sex, but the wife needs to "warm up" in advance to avoid the embarrassment of fully cooperating with her husband. After sex, the two can hug and talk to make up for the short foreplay.

Sex should be "what you want". You can leave more time for your partner on weekends and leave work and stress behind. Couples can stay in bed for a while, wake up their partner with kisses, and then enjoy some intimate time.
