Harmonious sex life is the reconciliation agent of the couple’s emotions. According to the survey, 80% of the couple’s relationship problems because of sexual disharmony, if you add the “unsatisfied” part, the proportion is up to 90% or more. And sexual disharmony, to a certain extent or with the sex position, unsuitable sex position, will often make love when the pleasure is greatly reduced. So, how should couples choose the right sex position? Common sex positions are the following: 1, male on female style is also commonly referred to as the normal position, the woman lying on her back, knees slightly curved and open, the man on top, and in the dominant position. Surveys show that more than 90% of couples will choose this sexual position, especially newlyweds, may be due to inexperience or shyness, but also often choose the traditional male-on-female style. In addition, it is clinically believed that couples who are in an active state of preparation for pregnancy choose this sexual position to improve the conception rate. And if there is a need for contraception couples can choose the standing or sitting position, after sex, the vast majority of semen will flow out of the body with the withdrawal of the penis, relatively speaking the chances of conception is extremely low. 2, female on male style such as riding style, the man lying on his back, the woman bent knees sitting on top, so that the upper body stand up or lean forward, backward, all with their own pleasure, and with the increase in pleasure, the waist movement will gradually intense, can give the penis to fully stimulate. When the woman is on top, the woman holds the initiative of sex and can better control the progress and strength of lovemaking. Clinically, this position is more suitable for men suffering from heart disease or physical weakness, and can also assist in the treatment of male impotence, premature ejaculation and female sexual indifference. 3, side entry that the woman is in the side lying position, the male partner from behind to enter. If one of the couple suffers from back injury, or waist is not good, you can use this position, not only the most effort, but also can better avoid touching the old problem due to excessive action. The shortcoming of this position is that in the process of lovemaking, the penis is easy to slip out of the vagina. 4, rear entry position that the woman remains prone, kneeling or bent over standing, legs apart, the man wrapped around and close to the woman’s back waist, slowly inserted, the position can make the penis easier to penetrate the vagina of women. This position allows the penis to penetrate deeper into the woman’s vagina. At the same time, the rear entry position has less chance of pressure on the woman’s abdomen, and is also the position doctors recommend pregnant women to take for lovemaking. Of course, some women may not like this position, because in the rear entry position, the two sides lack face-to-face eye contact, and will make the woman produce a psychological feeling of being oppressed; while for the male partner, when the male abdomen because of the action of penetration, and the female buttocks produce a patting sound, will increase its visual and auditory stimulation, thus enhancing its pleasure during lovemaking. In short, couples can choose the right sexual position according to their own situation and needs. If there is a need for pregnancy preparation, they can choose the male-on-female position to improve the conception rate; if there is a need for contraception, they can choose the standing position, sitting position, etc.; if it is lovemaking in the middle of pregnancy, they can choose the side-entry or back-entry position to avoid the pressure on the abdomen; of course, if they purely want to seek excitement, they can also use their imagination about sex and innovate new positions appropriately.
