How long after sex is it appropriate to urinate?

I believe everyone who has had sexual experience knows that urinating after sex is a very effective way of self-cleaning. Some men urinate immediately after sex, but others wait a while. So, how long after sex is the best time to urinate?

1. Urinating can reduce the chance of infection

There are many bacteria around the urethral opening of normal women. During sexual intercourse, due to collision and squeezing, these bacteria may enter the urethra through the urethral opening, and then go up along the urethra, causing diseases such as cystitis. At the same time, many bacteria grow in the smegma accumulated on the glans of the male penis, especially in the coronal sulcus, which can take the opportunity to enter the urethra and cause urinary tract infection.

In addition, the bacteria on the genitals of both spouses may take this opportunity to enter each other's urethra. Urine can effectively flush the urethra, wash away bacteria and reduce the chance of infection. Therefore, urinating promptly after sexual intercourse is a "health care" rule that both parties should keep in mind.

2. Urinating after the erection disappears

However, how long is considered "timely" is an issue that requires attention. In my clinical work, I found that, especially for men, it is best to rest after ejaculation and wait until the erection has basically disappeared before urinating. Before the penis becomes flaccid, the urethral sphincter is still in a tense state and the congestion has not subsided. At this time, urination may be difficult and it is easy to cause urine reflux. Over time, it may cause some prostate problems, which is not good for men's health.

Of course, the older you get, the more difficult it is to maintain an erection, and sometimes your penis may become flaccid before you even ejaculate. That way, after sex, men can go to the toilet after just a short break.

3. It is best to rinse your lower body with warm water

It should be noted that if conditions permit, men should rinse their lower body with warm water after sexual intercourse. Semen and female vaginal secretions easily stick to the external genitalia, especially the female perineum and male scrotum, providing a favorable environment for the survival and reproduction of bacteria. Timely cleaning can not only prevent external genital infection, but also reduce the chance of urinary tract infection.

4. Urinating and ejaculating do not interfere with each other

Do urination and ejaculation interfere with each other? The answer is no. Although the male urethra has both urination and ejaculation functions, the sphincter that controls urination and ejaculation is different. During urination, the bladder sphincter located at the neck of the bladder relaxes and the detrusor muscle contracts, allowing urine to be excreted from the body. The muscle that controls ejaculation is the membranous urethral sphincter that surrounds the middle section of the male urethra.

When a man is sexually excited, the bladder sphincter at the beginning of the urethra and the membranous urethral sphincter in the middle of the urethra are both in a contracted state, forming a closed cavity between the two sphincters.

Due to the rhythmic contraction of the smooth muscles of the epididymis and vas deferens, sperm is driven in and mixed with the secretions of the prostate and seminal vesicles. When the semen accumulates to a certain amount and the stimulation of the penis reaches a sufficient intensity, that is, when orgasm occurs, ejaculation occurs.

At this time, the membranous urethral sphincter relaxes, while the bladder sphincter remains contracted, and the accumulated semen will be ejected from the urethra. Obviously, under normal physiological conditions, urine leakage will not occur during ejaculation, and semen leakage will not occur during urination.

5. Semen is excreted from the body with urine

Some young men observe the urination process very carefully. Sometimes they can see that the urine is turbid. Is this because the semen is leaking out during urination?

After understanding the physiological process of urination and ejaculation, it is easier to discuss this issue. It turns out that young people have a relatively high sexual excitability. They are easily sexually excited by sensory stimulation such as vision, hearing, or local stimulation such as masturbation, which causes semen to accumulate in the urethra between the membranous urethral sphincter and the bladder sphincter. If ejaculation is not suitable or cannot be performed at this time, but the bladder is full and needs to be urinated, the semen originally accumulated there will be discharged from the body with urine.

It should be pointed out that this is not a pathological phenomenon. Every male adult will experience this situation, so there is no need to worry.
