Frequency and depth of thrusting (adult novel about sex)

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 penis thrusting. The higher the frequency of penis thrusting, the more opportunities there are for the penis and vagina to come into contact per unit time, which enables the sexual center to receive more information per unit time and stimulate sexual pleasure response. Penis: Its main functions are urination, semen discharge and sexual intercourse. 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 corpus cavernosum of the penis 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.
When the penis is thrust deeper, women will clearly feel the sexual impulse from the contact between the glans and the opening of the uterus, which can give women a pleasure that is completely different from the pleasure of clitoral friction. On the contrary, when the frequency of penis thrusting is lower and the penis thrusting is shallower, the sexual excitement of both parties will be weaker and the corresponding sexual pleasure will also be lower.

According to relevant foreign information reports, the frequency of penis thrusting is generally 1 to 2 times per second. When the frequency of penis thrusting exceeds 2 times per second, it can be considered high-frequency thrusting. The high-frequency pumping time can generally only be maintained for about 2 minutes.
When the pumping frequency is once every few seconds, it is low-frequency pumping. Low-frequency pumping is generally used to suppress male sexual desire and motivation to disperse sexual excitement energy, prevent ejaculation, and prolong the duration of sexual intercourse. The purpose of high-frequency pumping is to increase the sexual desire of both parties, concentrate the sexual excitement energy of both parties, and promote simultaneous orgasms to obtain the highest quality sexual pleasure.
Recommendation: Even with the thrusting motion, it is not just about in and out, it is best to have a varied motion. In particular, repeated insertion at a slow speed and with a shallow degree of penetration can make women in the excitement period impatient and restless. When women are anxious and looking forward to stronger stimulation, deep penetration can be given.

Generally speaking, the frequency of penis thrusting is inversely proportional to the depth of penis thrusting. That is, the higher the frequency of thrusting, the shallower the depth of penis thrusting.
