Sexual intercourse peristalsis method A little scientific summary and arrangement of the sexual intercourse movement methods such as "nine shallow and one deep" that were popular in the past can divide sexual intercourse movements into seven categories, namely forward and backward movement, up and down movement, compression movement, mixed movement, vaginal contraction branch and clitoral stimulation movement. If these male movements, female movements, and male and female coordinated movements are organically combined, more subtle sexual intercourse movements will be produced.
Forward and backward movement is the most commonly used method of sexual intercourse by men. Because it is similar to the movement of a piston in a cylinder, it can stimulate the anterior wall of the vagina, the cervix and other parts. However, this movement itself is very simple. In order to deepen the emotional atmosphere, it requires skills such as movement speed and depth. In the normal position, this forward and backward movement is close to horizontal. At this time, the uterus is pushed toward the head. Exercises such as women swinging their whole body can help increase the level of excitement. Women can also move back and forth in response to men's movements, but generally not as freely and flexibly as men.
The up-and-down movement is a typical exercise technique for women on top, front sitting or flexion positions, and is actually a variation of the forward-and-back movement. As we all know, it is difficult for women to perform this up and down movement as flexibly as men. This is because the erect penis of men is perpendicular to the body axis, while the vagina of women is roughly equal to the body axis. Therefore, when women do up and down movements, they should not be too intense, and it is very important to move slowly.
The rotation exercise is a technique in which the penis is inserted into the vagina and the waist is used to draw circles. It is most suitable for women in the bottom position. When doing the rotating movement, the two people are close together, which helps the base of the penis stimulate the vaginal opening.
Compression exercise is a technique that closely combines the sexual organs of two people after the penis is inserted. Through close pressure exercise, the female clitoris and uterine vagina are strongly stimulated, and the male can experience the pleasure of the contraction of the vaginal opening. Compression exercise can also be used as a short rest during sexual intercourse or as a technique to prevent male ejaculation.
Mixed sports is a diversified sports technique. Obtaining women's cooperation is an important prerequisite for mixed sports. Otherwise, it is impossible to achieve a rich and colorful sex life.
Vaginal contraction exercise is a technique that contracts the muscles of the vulva to increase sexual pleasure. Through training, the vagina can be tightened. The easiest way is to practice contracting the anus. The vaginal and anal sphincters are innervated by the same nerve. Therefore, when the anal sphincter contracts, the vaginal sphincter will inevitably contract as well. Strengthening and contraction exercises are not just for the pleasure of men. By contracting the vaginal opening, the sensitivity to stimulation is increased, which helps to enhance the sexiness of women themselves.
The most important clitoral stimulation exercise: The six sexual intercourse techniques have been introduced earlier, and the important one for women is the clitoral stimulation technique introduced in this section. No matter what kind of sexual intercourse is performed, if the clitoris is not directly or indirectly stimulated, it is not easy for women to reach orgasm. Men must understand this. Therefore, depending on the different body positions, it is necessary for men to caress the clitoris with their fingers while engaging in sexual intercourse.
