If you don't ejaculate during sex, your health is not guaranteed (adult novel about sex knowledge)

Having sex without ejaculation refers to suddenly stopping sexual intercourse when approaching climax, that is, before ejaculation, in order to prevent semen from being ejaculated out of the body.
This type of sexual intercourse is called "intermittent intercourse" or "interrupted coitus".
Intermittent sexual intercourse will not prolong life for both parties. On the contrary, it will be harmful to the body and mind of both men and women.
Harm 1: It can induce impotence and interrupt sexual intercourse halfway. The sexual center of the cerebral cortex, various sexual activity control nerves and various sexual organs are still in an excited state and cannot relax quickly, which invisibly increases the burden on the nervous system and sexual organs and causes a phenomenon of "over-fatigue".
The second hazard is that it can induce abnormal ejaculation. Interruption of sexual intercourse strongly inhibits ejaculation. If this happens frequently, it will cause ejaculation disorders. In mild cases, ejaculation is delayed and not rapid, while in severe cases, ejaculation is not occurring at all.
Hazard 3: It can induce aseptic prostatitis. After normal sexual intercourse and ejaculation, the penile erection quickly subsides, and the blood flow to the penis decreases by 50%-60% within a few minutes. After 10-20 minutes, the blood flow to the sexual organs will return to normal.
Harm four: It can induce hematospermia. For the same reason as the slow subsidence of congestion in the above-mentioned sexual organs, the seminal vesicle is extensively and persistently congested, and the capillaries on the seminal vesicle wall will expand and rupture, leading to hematospermia.
Harm 5: It can induce frequent nocturnal emission. During sexual intercourse, with the occurrence of sexual impulse, the secretion of various accessory glands increases and the amount of semen increases sharply.
