Back sex is the oldest form of human sexual intercourse, with primitive meaning or containing elements of animal sex. Since humans have evolved from animals, it is not surprising, but many people disdain this sexual position until they fully understand it. Back sex should be said to be a very distinctive form of sexual intercourse, where male and female positions cannot be replaced and can only be divided equally. There are several different forms of back posture. Women can have abdominal posture, kneeling posture, or bent standing posture. In abdominal posture, women are completely lying on the bed. In kneeling posture, women kneel on the bed with their elbows supported on the bed. In bent standing posture, women stand on both feet, with their hands or elbows supported on the bed, chair, table, etc., with their hips raised and their bodies parallel or bottomed. Men can lie completely parallel on the back of women, or kneel or stand. Kneeling posture is performed on the bed, while standing posture is suitable for performing under the bed.
The back in position is precisely because it is a primitive sexual position, which can be said to be a very perfect sexual intercourse method from a physiological and anatomical perspective. It is universally applicable to mammals and naturally also to humans. Firstly, the towering buttocks of women can cause extremely strong sexual attraction to men, causing obvious sexual excitement. However, the rich fat in women's buttocks acts like a sponge during sexual intercourse, forming a cushion for pressure, allowing both men and women to feel comfortable and happy. Men can take a dominant position in the sexual process, freely controlling the amplitude and frequency of twitching movements, especially for men with premature ejaculation. Whether to stop or continue halfway is entirely within their own control.
Women can actively cooperate with men in this position, especially when kneeling or standing, they can actively cater to men's pumping movements, and can also tighten vaginal muscles.
Some men complain that the vaginal muscles in women after childbirth are weak and not very sexy. It is advisable to adopt this position. It is best for women to lie completely prone in bed, while men kneel and ride on the women's buttocks. During delivery, they can lie prone on the women's backs or support their legs with both hands to clamp the women's legs together. At this time, the women's buttocks muscles, the inner muscles of the legs, and the muscle group at the vaginal opening can all participate in sexual intercourse, It provides a strong grip on the male penis, enhances sexual pleasure, and creates strong stimulation for male ejaculation. It also creates great vaginal stimulation for women, making it easy to form vaginal orgasm. It can be said that the back in position is the most likely sexual position to cause vaginal orgasm.
During back to back sexual intercourse, men can use their hands to stimulate the female breasts, clitoris, or touch the back, with a large range of movements and strong sexual pleasure. The disadvantage is that they cannot stimulate the female clitoris and are not suitable for women who only have clitoral orgasms. However, after multiple sexual encounters, most women can enjoy back to back sexual intercourse.
