Adults should be familiar with sex. Generally speaking, sex is a very secret private life, and it is destined to be the talk of everyone after a meal, and it is not going to talk about what is the perfect sex. To put it bluntly, perfect sex is far away from many people, because everyone feels that sex is an embarrassing topic and dare not go into it. Below, we will provide you with the 6 gold indicators of perfect sex. Welcome everyone to check in and see if you have achieved the standard? Criterion 1: At least two romantic contacts “For women, sex does not begin with undressing, but at the moment of contact with men.” British sex expert Dr. Bonnie Jacobson in his book It is pointed out that there should be at least two romantic contact opportunities in the first 1-2 days before sex, a small gift from a loved one, a romantic movie together, or a flirting text message at work. These actions will increase the expectation of sex, especially Let women enter the state faster. Standard 2: Do three “net, quiet, clean” Dr. Jacobson said that before sex, “bedding is clean, the environment is quiet, and the heart is clean.” Clean and tidy bedding is a prerequisite for sex, cotton sheets and large beds are the best choice. A quiet environment means no noise, no family disturbances. Clearness in the heart means that there is no side to heart, don’t worry about it. Standard 3: Foreplay reaches 6 minutes. Appropriate foreplay is important for both parties. It helps women to produce secretions in the vagina and helps men to increase erection hardness. Dr. Kurt, a psychologist and sexual therapist in Michigan, pointed out that the best “sexual foreplay” should satisfy the four needs of people’s vision, touch, smell and hearing, and talk about teasing, breathing, kissing and caressing… The time is usually 6 to 10 minutes. Standard 4: Substantial love 7 to 13 minutes Researchers at the Bilde College in Pennsylvania, USA, found that substantial love (sexual contact) is most appropriate in 7 to 13 minutes. More than 13 minutes, the male fatigue will increase, and it is more difficult to restore physical strength; less than 7 minutes, the two sides will not know what to expect. Standard 5: Embracing after 10 minutes afterwards, ignoring the “post-play” is a common problem for men all over the world, but the sex without the after-play is incomplete. Professor Ma Xiaonian from the Department of Sexual Medicine of Yuquan Hospital of Tsinghua University suggested that after each sex life, give each other some praise and encouragement, clean each other’s private parts, or say nothing, quietly embracing for 10 minutes, can give both sides psychological satisfaction. Deepen each other’s feelings. Standard 6: A new survey conducted by the Institute for the Correction of Contraceptive Measures shows that good contraception can make both parties have no worries and enthusiasm in sex. Contraceptives and condoms are good choices Choose. Of course, if you have decided to have a baby, then relax and enjoy. Perfect sex is also a scientific love. These standards are the result of scientific research. If you accidentally reach the standard, it means your sex is still very high. If your individual criteria are not met, don’t worry, people are not perfect, as long as we have goals in our hearts. Of course, if you don’t meet a standard, then you and your partner will have to refuel!
