Four harmful taboos for men after sex

Don't urinate right away

Urinate immediately after sex to flush the urethra and avoid infection. For women, urinating immediately after sex is a simple and effective way to prevent urinary tract infection. Because women's urethra is short and straight, during sex, bacteria from the vulva may retrograde into the urethra, causing urethritis, cystitis, etc. However, experts say that men should not rush to urinate after sex, otherwise it will cause damage to the prostate, because men's urethra is long and curved, and the resistance to urine passing through is large and takes a long time.

After sexual intercourse, the congestion of the corpus cavernosum of the penis has not subsided, and the contraction of the urethral sphincter and detrusor has not been eliminated, which causes high urethral resistance, leading to difficulty in urination or even inability to urinate. If you are eager to urinate at this time, the pressure in the urethra will increase, and urine with bacteria and metabolic waste will flow back into the prostate. If this continues for a long time, it is easy to cause prostatitis. Experts suggest that men should rest for 5 to 10 minutes after ejaculation and urinate after the congestion disappears.

Can't fall asleep right away

Men generally feel tired after sex, so many people like to fall asleep, thinking that this will eliminate the fatigue. In fact, the opposite is true, which will make the fatigue after ejaculation last until the next day. Usually, when a couple has sex, from the beginning of sexual excitement to the end of orgasm, under normal circumstances, it lasts about 5 to 20 minutes, but it can be longer than this. During sex, the sympathetic nerves of the human body are in a highly tense state, and the secretion of various hormones, especially sex hormones, is vigorous.

At this time, not only are the sexual organs of both parties in a highly congested state, but also many tissues of the body are involved in this special physiological process from the sexual excitement stage to the climax stage, such as: faster heartbeat, increased blood pressure, deeper and faster breathing, dilation of blood vessels in the skin, increased perspiration, etc. Therefore, in this process, the body's energy consumption increases significantly and metabolism is enhanced.

The reason why you feel tired after sex is mostly because the reflex function of the brain and spinal cord that controls the discharge of semen relaxes temporarily after ejaculation. The nerves are excited and tense during ejaculation, and the nerves and spinal reflex nerves relax after ejaculation. If you do not go to sleep immediately after sex, but get up and continue to do some daily things, the reflex nerves that have become dull due to sexual stimulation can recover smoothly. If you fall asleep immediately after sex, the dull effect of sleep plus the dull effect of sexual stimulation will make the fatigue continue until the next day, leaving you with back pain.

Things that cannot be eaten immediately after cooling down

During sex, people often feel hot and thirsty. Eating cold food will not have any adverse effects on the reproductive system. Because the changes caused by sexual excitement are only concentrated in the sensory nervous system and the endocrine system, as the sexual excitement subsides, these changes will slowly return to normal. Even if eating something cold has a stimulating effect, it is not limited to the digestive tract. However, during sex, the sympathetic nerves are more excited, and the blood in the gastrointestinal tract will also decrease compared to usual. Therefore, drinking ice water immediately before the congestion of the gastrointestinal mucosa returns to normal will cause the gastrointestinal mucosa to suddenly become cold, causing certain damage to the gastrointestinal tract.

In severe cases, it may also cause gastrointestinal discomfort or colic. Whether it is summer or winter. Experts suggest that if you feel thirsty after sex, you may drink a small amount of warm or cold boiled water, and try not to drink ice water or cold beverages. For those who originally suffer from gastroenteritis, indigestion, and ulcers, even if they do not have sex, it is not good to eat too much cold food. It can be seen from this that eating cold ice cream, popsicles, etc., whether you have sex or not, should be limited according to your own gastrointestinal function and should not be eaten without restraint.

Can't blow dry immediately

After sex, you will probably sweat a lot. Men like to blow air directly to the air conditioner naked, which is wrong. This will easily give germs an opportunity to take advantage. After sex, the body's ability to regulate body temperature will weaken, making it easy to catch a cold. In addition, blowing cold air directly will cause the sweat glands to suddenly close, making it impossible for sweat to be discharged. Therefore, even in the hot summer, you should avoid blowing cold air to the air conditioner without clothes, and cover yourself with a thin blanket.
