82% of people use unsuitable condoms. Common condoms have many disadvantages.

A survey conducted by relevant agencies showed that of the 3000 men aged 16 and 60, only 18 per cent chose suitable condoms, while the remaining 48 per cent used condoms that were too large and 34 per cent used condoms too small. These problems are not really about condoms, but because people are too casual in their choices.

How to use condoms correctly

1. It feels best to store it for one year.

Condoms are not as fresh as food and are most suitable for use within 1 or 2 years after they leave the factory. Condoms that have just left the factory have poor elasticity and texture. After storage for half a year to one year, the latex will have a certain degree of physical or chemical reaction with the lubricant, and the texture and elasticity will reach the best state. The factory for more than 3 years, not only easy to brittle, the internal added lubricant is almost absorbed by the latex, the lubrication effect is greatly reduced.

The appearance of particles or thread protruding ed vacuum pump , or fragrant, color fun condoms will add other substances, more prone to aging, which will also increase the risk of allergies, when using should pay attention to the body's feelings.

2. Ejaculate quickly, don't use ultra-thin sleeve

Condoms can be divided into ultra-thin, thin and ordinary three types. In terms of physical perception, the thinner the condom is, the closer the man thinks he is to his partner and the stronger his pleasure; the thicker the condom is, the more limited the sensitivity of his penis to sex, and the worse he feels.

However, men with faster ejaculation are not suitable for ultra-thin products. Use a thicker condom, on the contrary, it will help to prolong the time of sex, so that both sides get more pleasure.

3. Choose the right model and use less fragrance covers

People in different regions have different physical characteristics, and condoms have different sizes. In most cases, the size of the condom suitable for most men in China is medium. If you feel too tight or too loose after using it once, use a thin thread to circle the middle of the penis after a full erection, and then measure the length of the line, which is the perimeter of the penis, divided by 2, and then according to this calculation, consult to buy a condom of the right size.

Today's condoms are colorful and smelly. This can improve people's aversion to condoms and increase sexual attractiveness. But the spices added may cause vaginal inflammation in the female partner. When choosing this kind of product, it is best to buy a small package. If it is uncomfortable, it can be discarded without great loss.

4. Wear a condom without an erection, it is easy to fall off

Wear condoms to pay attention: should be put on after a complete erection of the penis, otherwise it will make the condom appear superfluous wrinkle, easy to slip off. Secondly, if after wearing, there is still no formal sexual intercourse after caressing for a long time, it will make the surface of the condom dry and not easy to insert into the female vagina. Therefore big ass anal , it is best to be caressed by both sides, wait until the degree of excitement increases, and then put on the condom, and make sure that the end of the condom curl is exposed on the outside. After sex, you should immediately press the bottom of the condom with your hand when the penis is still erect, and take off the condom after the penis is completely removed.

The disadvantages of commonly used condoms semen can resist bacteria, reduce inflammation and fight cancer.

At present, although the problem that semen can promote women's health has not been fully and authoritatively affirmed, many experts and scholars have pointed out after research that the health care role of semen can not be ignored.

1. Can resist bacteria and reduce inflammation

In a biological experiment, German medical scientists accidentally found that men's semen contains an important antibacterial substance-semen cytoplastin. This special functional substance, once in the bacteria controller vibrator , can prevent the synthesis of bacterial ribonucleic acid, bacteria will not be able to survive.

Laboratory culture found that semen cytoplasmin can kill staphylococci, streptococci and other pathogenic bacteria like penicillin, streptomycin and tetracycline. Some people conducted gynecological examinations on 100 women who had been married for more than 30 years and had harmonious sex once or twice a week. The results showed that only 10% of them suffered from gynecological diseases such as vaginitis, cervicitis, endometritis, salpingitis and so on. The incidence rate is much lower than that of women who have less normal sexual life.

The reason is that women who have normal and harmonious sexual life often have semen from their husbands in the reproductive tract, and it is the antibacterial and anti-inflammatory effect of semen that reduces the incidence of reproductive tract infections in these women. Condoms have made important contributions to human beings in contraception and preventing the spread of sexual diseases. However, while preventing male semen from entering the female reproductive tract, it may also "trap" women's health.

two。 Can fight cancer.

Studies have found that semen can fight against ovarian cancer in women. They injected the active components extracted from sperm-removed semen into the culture medium containing epithelial ovarian cancer cells and ordinary ovarian epithelial cells, respectively. Forty-eight hours later, they found that the death rate of ovarian cancer cells was 81%, while that of normal cells was only 37%.

In addition, semen can also promote female sex hormone secretion, make breasts plump, buttocks plump, skin delicate; can moisten the vagina, improve the quality of sexual life, enhance sexual psychological satisfaction, is conducive to play the role of sexual health care. Condoms have made important contributions to human beings in contraception and preventing the spread of sexual diseases. However, while preventing male semen from entering the female reproductive tract, it may also "trap" women's health.

Is your condom the right size?

According to the international standard, the longest condom is 198 mm, the thickness of the condom is 0.06 mi 0.07 mm, the thickness of the ultra-thin condom is only 0.03 mm, and the average weight is 1.4 grams. The stretch should be 7 times that of the original, and it takes a force of 13 kilograms to tear it in half. There are three types of condoms in China, namely, large (35mm), medium (33mm) and small (31mm).

Clinical statistics show that many men use condoms that are too tight, which block the blood circulation of the penis and lead to ischemia, lack of oxygen to the tissue and nerves in the penis, and easy injury to the part of the cavernous body, which leads to weakness and failure of the penis. Serious cases even lead to sexual impotence. Experts suggest that when choosing condoms, you must use the standard size of condoms, and do not buy and use condoms casually. Before having sex, according to the size of your penis and the opinions of each other, choose the style and model that you need to ensure that the penis tissue will not be bruised.

Condom production and sales market chaos also brings greater confusion to consumers, and even leads to unsafe use process. It is understood that at present, the supply channels of the domestic condom market are quite chaotic, and wholesale can be carried out in family planning medicine management stations, condom production enterprises, middlemen, small traders, and even various industries. Product quality is even more worrying: there are only 7 condom designated enterprises in the country, but there are hundreds of Packers and thousands of brands.

Among them, 30% of the products are fake and shoddy. The tearing rate of ordinary quality condoms is 1%, while that of high quality condoms is only 1%. The front end of a few condoms may have holes that are difficult to see with the naked eye, and although sperm cannot pass through, they may still become a door for the virus to sneak through. Because HIV is only 0.1 microns in diameter, 30 times smaller than sperm, and almost all STD viruses are so subtle, even if some condoms can provide contraception, they may not be able to prevent the disease.
