Couples and spouses must remember these numbers

When it comes to sex, everyone's sexual experience is different, and it is impossible to force everyone to have the same sexual experience. However, knowing more about the scientific knowledge about sex is still very helpful in improving sexual experience and increasing the chances of harmonious sex. Here, experts have summed up some interesting little numbers about sex.

Best time for sex: 7 a.m.

7 o'clock in the morning is the peak time of sexual desire for men and women. According to the American Sex Survey, there is a time difference in sexual desire between men and women, but 7 a.m. is when both men and women are most sexually active. At this time, the levels of sex hormones in men and women are at their highest, and men also have morning erections, so the quality of sex will be more ideal.

Ideal foreplay time: 8 minutes

Sex without foreplay is tasteless and will make women feel disgusted. In addition, women do not produce enough secretions, and penetration will be particularly difficult. A French study suggests that for the average couple, foreplay lasting about 8 minutes is more appropriate. If you spend twenty or thirty minutes on foreplay, men may become weak.

Best sex time: 7 minutes

This sexual time refers to the time from insertion to ejaculation. Experts from Utrecht University in the Netherlands conducted a study on 491 couples in five countries and found that actual lovemaking lasts 3-7 minutes, which is enough to satisfy needs; 7-13 minutes is desirable; less than 3 minutes is too short, and more than 13 minutes may be too long. Overall, 7 minutes of sex gives the highest satisfaction.

Post-coital warm-up time: 5 minutes

Ignoring "after play" is a common problem among men all over the world. A survey in the United States shows that 72% of men ignore the period after sex. But at the same time, 31.6% of women want men to "hug her for at least 5 minutes" after sex, and 25.9% of women want men to ask her "if she is happy and comfortable." Therefore, experts recommend that both parties rest for 5 minutes after sex. A warm hug or washing together are both good choices.

Women's sexual desire fluctuates every 14 days

Maris Topps, a female scientist at the University of London, discovered that women have two regular peaks of sexual desire every month, generally 14 days apart and each lasting 3 days. This change in women's sexual desire is related to the secretion of hormones during the menstrual cycle.
