Introduction to the seven categories of sexual intercourse

　　

       A little scientific summary and arrangement of the sexual intercourse exercise methods that were popular in the past, such as "nine shallow and one deep, three right and three left...", can divide sexual intercourse exercises 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. _Sexjk.com
　　
1. Forward and backward movement
　　
The forward and backward movement is the most common method used by men in sexual intercourse. Because it is similar to the movement of a piston in a cylinder, it can stimulate the front wall of the vagina, the cervix and other parts. This movement itself is very simple. In order to deepen the emotional atmosphere, it is necessary to have skills in movement speed and depth. In the normal position, this forward and backward movement is nearly horizontal. At this time, the uterus is pushed toward the head. Women's whole body swinging and other movements can help increase the degree of excitement. Women can also do forward and backward movements corresponding to men's peristalsis, but generally they cannot be as free and flexible as men.
　　
2. Up and down movement
　　
It is a typical exercise technique for women in the top position, front sitting position or flexion position. It is actually a variation of forward and backward movement. As we all know, it is difficult for women to do 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 movement, it is important not to be too intense and to move slowly.
　　
3. Rotational motion
　　
It 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 lower position. When doing the rotation exercise, the two people are close together, which helps the base of the penis stimulate the vaginal opening.
　　
IV. Oppression Movement
　　
It is a technique that closely combines the sexual organs of two people after the penis is inserted. Through close pressure movements, the female clitoris and uterine vagina are strongly stimulated. The male can experience the pleasure of the contraction of the vaginal opening. The pressure movement can also be used as a short rest during sexual intercourse or as a technique to prevent male ejaculation.
　　
5. Hybrid Sports
　　
It is a diversified sports skill. Obtaining the cooperation of women is an important prerequisite for mixed sports. Otherwise, it is impossible to achieve a rich and colorful result.
　　
6. Vaginal contraction exercise
　　
It is a technique to contract the muscles of the vaginal opening to increase sex appeal. Through training, the vagina can be very tight. The simplest method is to practice contracting the anus. The vaginal sphincter and the anal sphincter are innervated by the same nerve. Therefore, when the anal sphincter is contracted, the vaginal sphincter will inevitably contract as well. The practice of strengthening and contracting strength is not just to please men. By contracting the vaginal opening to increase the sensitivity of the response to stimulation, it helps to enhance the sex appeal of women themselves.
　　
7. The most important clitoral stimulation exercise
　　
Six sexual intercourse techniques have been introduced above, and the most important one for women is the clitoral stimulation technique introduced in this section. No matter what kind of sexual intercourse is done, if the clitoris is not stimulated directly or indirectly, it is not easy for women to reach orgasm, and men must understand this. Therefore, according to different positions, it is necessary for men to caress the clitoris with their fingers while doing sexual intercourse.
　　
So far, not enough attention has been paid to caressing during sexual intercourse. Even if it is considered necessary, it is only considered as an auxiliary technique. However, if there is a lack of stimulation of the female clitoris during sexual intercourse, it is like a lack of stimulation of the male penis, making the sexual intercourse boring.
