The dangers of intentionally withholding ejaculation during intercourse, the relationship between penis size and sexual pleasure, and the need for caution when using medication.
Can intentionally holding back ejaculation during intercourse preserve "vital energy" and prolong life?
"Food and sex are human nature," and sexual activity is a basic human instinct, fundamental to human reproduction. For men, reaching orgasm and ejaculation is a key part of the sexual process. If intercourse is stopped before reaching orgasm and ejaculation, it is called "incomplete intercourse." This not only prevents both partners from achieving full physical and emotional satisfaction, leading to disharmony and sexual happiness, but also prevents the congestion of the reproductive system from dissipating quickly. The cerebral cortex and spinal cord remain in a state of excitement for an extended period, and accessory glands such as the seminal vesicles are not fully emptied. This prolonged state of excitement without rest leads to fatigue and, over time, can cause chronic nonbacterial prostatitis and seminal vesiculitis in men.
It is a normal physiological phenomenon for healthy men to experience nocturnal emissions 1-2 times per month. Married men who have not had sexual intercourse for a long time may also experience nocturnal emissions. Therefore, even if one intentionally does not ejaculate during intercourse, it does not guarantee that semen will not be leaked. In fact, of the 2-5 ml of semen ejaculated during each sexual intercourse, 95% is seminal plasma (the main component of seminal plasma is water, accounting for about 90%), sperm accounts for only about 1%, and the rest are small amounts of proteins, fats, and other substances. Even if sperm is not ejaculated, it will age, die, and eventually be digested by enzymes. The British Medical Journal has clearly stated that "frequent sexual intercourse can satisfactorily maintain a long life and is beneficial and enjoyable for both partners." Therefore, the theory of "not ejaculating during intercourse" and "cherishing semen" to preserve "vital energy" and prolong life has no scientific basis. On the contrary, it can lead to some diseases.
Is penis size related to sexual pleasure and orgasm?
The size of a man's penis varies greatly depending on individual differences (such as height, weight, strength, and weakness). Some men have large and long penises when erect, while others have relatively small and short ones. However, this does not affect normal sexual intercourse; in other words, the size of a man's penis does not prevent a woman from reaching orgasm. During the "plateau" phase of a woman's normal sexual response cycle, the outer third of the vagina experiences significant vascular congestion. This response, medically known as the "orgasmic plateau," results in the narrowing of the vaginal opening, creating a "gripping" effect around the penis. Even for a relatively small penis, this gripping effect is sufficient. Furthermore, the vaginal mucosa has transverse folds and considerable extensibility. Combined with the abundant secretions and exudates that lubricate the vagina during sexual arousal, even a relatively large penis can be accommodated. Therefore, the size of the penis during intercourse is not a significant factor in the physical stimulation felt by the woman. During orgasm, the upper two-thirds of the vagina expands, and the smooth muscles in this area relax. This reduces direct stimulation of the distal vagina and cervix during penile thrusting and also helps retain ejaculated semen. From a neurological perspective, the inner two-thirds of the vagina has almost no sensory nerve endings, while the outer one-third, the area where the orgasm platform forms, is richly endowed with them. Therefore, sexual arousal and orgasm are determined by the outer one-third of the vagina and the clitoris, and are unrelated to the length or size of the penis. Even with a small penis, as long as sexual function is normal or good, successful intercourse can still lead to sexual happiness.
Why should one be cautious about taking sex-enhancing drugs before intercourse?
Men often find it difficult to talk about sexual dysfunction. Faced with the fierce competition in the sexual health product market – with brands like AiGe, QiangGe, MengGe, and WeiGeWang – and often misled by unscrupulous advertisements, unlicensed doctors, or street-corner leaflet experts – sexual health damage is all too common. Therefore, men are advised that if they experience sexual dysfunction, they must seek treatment at a reputable hospital's urology department.
Studies show that few men with erectile dysfunction actually seek proper treatment at hospitals. Although Viagra is currently the most effective drug for treating erectile dysfunction, it is rarely accepted in China for three reasons: first, traditional beliefs discourage patients from seeking treatment from urologists at reputable hospitals; second, there are too many advertisements for treating sexual dysfunction, leading many to follow these claims; and third, there are not enough urologists in reputable hospitals.
Many so-called sexual enhancement supplements labeled "take one hour before intercourse" currently contain the banned drug sildenafil, yet they fail to list the contraindications for sildenafil, which is very dangerous. This is because this drug cannot be taken with nitrates, as doing so could be life-threatening.
