Why is it still soft after ejaculation?

It is a normal physiological phenomenon that the penis does not become weak immediately after ejaculation. It is usually related to factors such as continued sexual excitement and delayed subsidence of congestion. The main reasons include the persistence of sexual stimulation, individual differences in sensitivity, residual prostatic fluid, age-related functional changes, and the influence of medications.

1. Continuous sexual stimulation:

If there is still visual, tactile or psychological stimulation after orgasm, the cerebral cortex will continue to send excitement signals, prompting the corpus cavernosum to remain partially congested. This situation is more common in scenes with short intervals between sexual intercourse or intense sexual fantasies. It usually subsides naturally within 10-30 minutes.

2. Difference in sensitivity:

There are individual differences in the distribution density of penile nerve endings. Those with lower sensitivity may take longer to complete the attenuation process of nerve signal conduction. Clinical observation shows that about 15% of healthy men experience complete weakness for more than 30 minutes after ejaculation.

3. Prostatic fluid residue:

After ejaculation, the smooth muscle of the prostate may contract rhythmically, resulting in the continued secretion of a small amount of prostatic fluid. This local stimulation will reflexively maintain a partial erection through the pelvic nerve, and is common in situations where sexual arousal is high or abstinence is long.

4. Age factor:

In men over the age of 35, the elasticity of blood vessels gradually decreases, and the return rate of the cavernous body veins slows down. Data shows that the time for complete weakness after ejaculation in men aged 40-50 is on average 8-12 minutes longer than in adolescence. This is a manifestation of the natural aging of vascular function.

5. Drug effects:

Some antidepressants such as paroxetine and antihypertensive drugs such as terazosin may interfere with autonomic nervous system regulation. These drugs cause a prolonged state of relaxation of the smooth muscle of the corpus cavernosum of the penis by affecting alpha adrenergic receptors.

It is recommended to observe whether it is accompanied by pathological manifestations such as pain and priapism for more than 4 hours. Daily cold compresses on the perineum and urination and flushing of the urethra can be used to promote resolution. Maintaining a regular sexual frequency 2-3 times a week will help maintain normal vascular reflex function and avoid long-term abstinence or excessive frequent stimulation. People over 40 years old can appropriately supplement 15 mg of zinc and 100 IU of vitamin E per day to improve microcirculation. However, if the abnormality persists, the possibility of priapism or blood system diseases must be ruled out.
