Sex life in today's society has become an indispensable part of people's daily lives. Life without sex can be said to be boring. Of course, while having sex, both partners will also use various sexual methods to have sex. Helps sexual intercourse, but improper sexual intercourse methods may cause harm to the body.

So what types of sex can harm your body?

1. There are no safety measures.

Semen contains a large amount of protein, including dozens of specific antigens. If the woman is allergic, having sex without safety measures will often induce a series of allergic reactions, such as sudden chest tightness, vaginal burning, pain and itching, etc. Sometimes, the man takes some medicines or eats certain foods before sex, which may also cause allergies in women. What's more important is that even couples may not know whether each other's private parts contain certain viruses and bacteria. Adopting unsafe sex methods may sow dangerous seeds for health.

2. Deliberately extend the time.

Most men always want to use various methods to delay ejaculation, but resisting ejaculation will lead to excessive pelvic congestion, which will increase the burden on the sexual nervous system and sexual organs. On the one hand, it will reduce male sexual desire and induce erectile dysfunction; on the other hand, it will easily induce reproductive dysfunction. Systemic infections such as chronic prostatitis. What's more, it may cause semen to "go through the back door" and cause retrograde ejaculation, that is, semen enters the bladder and is then excreted out of the body with urine, thus affecting fertility.

3. Continuous sex.

After having sex for the first time, the excitability of a male's penis decreases. If the penis is required to erect again immediately, it can easily induce autonomic nervous system dysfunction, cause prostate congestion, and relax and expand the glandular ducts, endangering the health of the prostate. Excessive sperm loss may also reduce the function of the anterior lobe of the pituitary gland, increase the burden on the testicles, and accelerate male aging. Continuing to have sex for the second time will also make the female pelvic cavity congested for a long time, which may even take 4-6 hours to subside. Over time, lower abdominal distension, pain, and even dysmenorrhea are likely to occur.

4. Lack of foreplay.

Women's sexual desire is slow and weak, and sexual excitement appears later. Therefore, if there is a lack of foreplay in sexual life, it is generally difficult for the man to move the woman, and it may also lead to insufficient secretion of accessory gonad fluid and no lubrication. Rough and hasty movements can easily arouse the woman's disgust or cause pain. Generally, sexual foreplay lasts about 15 minutes.

5. The posture is not suitable.

Improper posture during sex, resulting in too much force on one side of the waist, may cause backache, pelvic floor and gluteal muscle spasm, and lead to erectile or ejaculation dysfunction. Especially obese people have poor body flexibility and flexibility and are more prone to problems. Therefore, the fatter person should be on the bottom as much as possible. If both husband and wife are heavier, side positioning can be considered.

Precautions for sexual life

1. Reproductive organs should be kept clean. Both men and women should be considerate and keep their external reproductive organs clean. In addition to regular bathing, the external genitalia should also be cleaned frequently with warm water, and should be washed before and after each sexual intercourse. In this way, men can prevent foreskinitis and balanitis; women can prevent inflammation of the reproductive organs and ulcers of the urinary system. During sexual intercourse, both men and women should urinate as soon as possible, which is conducive to the discharge of bacteria into the bladder and can reduce the occurrence of ulcers.

2. The number of sexual intercourse should be determined. Be careful not to use it too frequently to avoid pulling it out of normal condition. During the wedding period, the sexual health of couples becomes more prosperous as they age, and their sexual needs become more urgent, so they should be considerate and temperate. For normal young men and women, having sex 3-4 times a week in the early stages of marriage is not too much, but for people with poorer health, sexual intercourse should be longer and less frequent. How long is the appropriate interval? It depends on the couple’s age, physique, normal events, psychological patterns and motives. Factors such as emotion and degree of weakness. Generally speaking, the principle is to not feel tired after sex and not to be distracted from work and study.

3. It is not suitable to have sex during hard work. When both or one of them feels tired, they should take a break to allow their energy and physical strength to recover. It is uncomfortable to have sex during this period. If men have sex during hard times, not only will their sexual pleasure be reduced, but their post-coital fatigue will also increase. They will suffer from headaches, dizziness, loss of energy and lack of energy the next day, lack of motivation to go to work, and sore waist and heavy legs. , it is easy to convey diseases such as premature ejaculation, impotence, etc.; the woman gathers together due to hard work, and it is easy to convey the sorrow of the sex life, which may lead to the formation of unmotivated or hateful sex in the future.

4. Sexual intercourse should be completed during the illness period. If one of the couples is suffering from a disease, especially in the acute stage of the disease or suffering from an acute festering disease, sexual intercourse should be temporarily discontinued, because the disease itself has already exhausted the body, and sexual intercourse will further consume physical energy and make the body resist the gravity of the disease. Reduction can lead to reversal of the disease, especially when one party has an infectious disease, and the disease may be transmitted to the opponent. In addition, due to the pull of diseases, the normal state of sperm or eggs can sometimes be destroyed. When a woman suffers from certain diseases, the internal environment of the uterus may become unfavorable for the development of fertilized eggs. If pregnancy occurs after intercourse at this time, it is unlikely to occur. Normal sperm-egg aggregation can produce abnormal fertilized eggs. Such fertilized eggs survive in an inconvenient intrauterine environment, and the fetuses conceived will have many reversal effects.
