During sex, many men fail to control the frequency and depth of thrusting, causing women to miss out on orgasm. There are techniques to thrusting, and women want you to do this the most...
In sexual life, it is very important for men to make women orgasm easily and the thrusting technique is very important. The sexual pleasure achieved by both men and women, in addition to the duration of sexual intercourse, is also closely related to the frequency and depth of the man's thrusting.
The theoretical basis for the depth and frequency of twitching is the penis: its main functions are urination, semen discharge and sexual intercourse, and it is the main organ of sexual behavior. The skin of the penis is extremely thin, there is no fat under the skin, it is mobile and stretchable, and the blood sinuses of the penis corpus cavernosum can absorb blood.
Vagina: The vagina is a cylindrical muscular tube connecting the external genitalia and the uterus. It is a woman's sexual organ and the channel for menstrual blood to be discharged and the fetus to be delivered. The vagina is about 10 cm long, wider at the upper end, and forms a ring-shaped groove around the cervix of the uterus, called the vaginal vault.
Therefore, the higher the frequency of thrusting, the more opportunities for contact per unit time, which can enable the sexual center to obtain more information per unit time, making it easier to stimulate sexual pleasure response.
Even with the thrusting motion, it is not just about in and out, it is best to have a movement with variations. In particular, repeated insertions at a slow speed and with a shallow depth of penetration can make women in the excitement stage impatient and restless. When women are anxious and looking forward to stronger stimulation, deep penetration is given. Generally speaking, the frequency of thrusting is inversely proportional to the depth of thrusting. That is, the higher the pumping frequency, the shallower the pumping depth.
Some techniques related to thrusting. In order to obtain high-quality sexual pleasure, in addition to the frequency, depth and duration of thrusting, it is also related to factors such as the caliber and length of the female's penis, the size and length of the male's erection, and the degree of lubrication of the female's secretions.
Once they have come together, inexperienced men will move back and forth, making violent thrusting movements in order to capture their own pleasure. However, thrusting alone is not sex. Just like body positions, various variations, clever combinations, and changes can enhance women’s pleasure and guide them to orgasm.
The rotational movement is a movement of the waist in the shape of a "?", which is like a circle drawn inside. Because the mouth is used as a fulcrum, the whole vaginal wall is stirred in the middle, which can bring women a strong pleasure. In a state of deep union, the pubic bones rubbing against each other is a compression movement. Gently moving the waist back and forth in a circular motion can stimulate the clitoris, but because men themselves are less stimulated, this exercise is suitable for use in intercourse that lasts for a long time.
