What are the points for high-quality intercourse? All couples know that couple life is a very good thing, but not every sex can achieve good results. Sometimes, sex is not good. The effect will also destroy the feelings between husband and wife, which requires couples to communicate more when they are sexual, so what are the points needed for a high-quality sexual intercourse. First, do three “net, quiet, net”. Before sex, it is necessary to “be clean, quiet, and 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. Second, the foreplay reaches 6 minutes. Appropriate foreplay is especially important for both parties. It helps women to produce secretions in the vagina and helps men to increase erection stiffness. Dr. Kurt, a psychologist and sexual therapist in Michigan, pointed out that the best “sexual foreplay” must meet the four needs of people’s vision, touch, smell, and hearing. Let’s talk about teasing, breathing, kissing, and caressing… The time is generally 6 to 10 minutes is more appropriate. Third, 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. Fourth, hug for 10 minutes afterwards. Not paying attention to the “post-play” is a common problem for men all over the world, but the sex without the after-play is not complete. 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.
