90% of men choose condoms casually. Four birth control methods will destroy women.

When it comes to condoms, adults are no stranger, but have you carefully examined the condoms you use as much as you choose other products? There are all kinds of condoms sold on the market. Some condoms are not only in packaging and names, but also in a variety of products, including threaded, dotted, striped, colorful and emitting different fragrances. There are even condoms with scalable semen as the selling point. Yesterday, the reporter interviewed nearly 10 men and found that 90% of the men did not know how to choose the one that suits them.

What do you value when choosing condoms?

What do you look at first when choosing a product? Is it the price? Brand? Or function? The reporter found in the interview that many men's choice of condoms is blind.

In the interview, most men said that when choosing condoms, they would first look at their price or brand. Some men may choose according to their fragrance and thickness, but few people look at the number of condoms. "in fact, when choosing a condom, under the premise of qualified quality, you should first consider the number that suits you." Ding Degang, chief physician of urology in Henan people's Hospital, introduced. However, most of the condom numbers on the Chinese market are medium, which also sets up obstacles for many men to choose.

Don't make do with the size of the condom.

The reporter found in a number of drugstores and supermarkets that the types of condoms sold were unexpectedly "consistent": only 52mm, that is, medium-sized condoms. And even salespeople do not know the difference between models, but vaguely say that "there is not much difference in size" or "this is an average size, big or small", even if they are condoms of some international brands best penis pump , they are all medium sizes.

After consulting several men, the reporter learned that many of them also have questions about the size of condoms, but most of them will not stubbornly find what suits them, so they will make do with medium size, and some people even think that there is only one type of condom. In addition, men usually pay attention to face, do not want others to know their privacy, feel uncomfortable, then have to make do with it.

Chen Qian, chief physician of the urology department of the first people's Hospital of Zhengzhou, analyzed that Asian men are recognized as having shorter genital sizes than Europeans and Europeans. In most cases, the suitable condom size for Chinese men is medium vibrators for women , which is also the reason why medium condoms dominate the market. "but clinically, we often see that some men's penile blood circulation is blocked due to the use of tight condoms, resulting in lack of oxygen in the penile tissue and nerves, injury to part of the cavernous body, and even weakness and failure to lift the penis; and some people buy too large condoms, which can easily lead to condom shedding and semen outflow, reducing the effectiveness of contraception. Therefore, whether from the perspective of safe contraception, prevention of sexually transmitted diseases, or from the perspective of improving the quality of sex life, you should choose the number that suits you. " Chen Qian said. "although few, but there are a small number of large and small sets on the market, run a few stores should be able to find suitable sets." Chen Qian suggested that men should look for more places where family planning stores such as drugstores are concentrated, and they should be able to find suitable ones.

Sex condoms should be used with caution

In addition to the size of condoms, what other considerations should men do when choosing condoms? Experts suggest that the selection of condoms should also pay attention to the material, shelf life and other elements. "it is recommended that men pay attention to the factory date when choosing condoms, and it is best to buy small packages and condoms that leave the factory for one to two years. On the one hand, it can be used up as soon as possible in the shelf life to prevent the lubricant from being over-absorbed by the latex. On the other hand, if it is uncomfortable, you can give up using it best ass , and the loss is not great. " Ding de just introduced.

As for more and more sex condoms on the market, Chen Qian's suggestion is that sex condoms add other substances to make them more brittle and aging, and at the same time, the substances added may also cause allergies among users. You should be very careful when choosing, "you might as well choose a small number of different brands or different series of the same brand when buying, like buying clothes, try it once or twice." Then choose the brand and series that are the most satisfactory to use.

Four birth control methods can destroy women.

Ejaculation in vitro:

In vitro ejaculation method refers to sexual intercourse, when the man will have a sense of ejaculation, that is, before ejaculation, the penis will be extracted from the vagina in time, the semen will be ejected to the outside of the vagina, so that the sperm can not meet the egg, so as to achieve the purpose of contraception. It's easy to get pregnant using this method. Because during sexual intercourse, men often have a little semen flowing into the vagina with prostatic fluid before ejaculation, or when sexual pleasure reaches the extreme, the action of pulling out the penis is a little slower ("heat" is difficult to accurately grasp), and part of the semen has been injected into the vagina, resulting in the failure of contraception. In addition, this method is easy to make both men and women nervous because they pay too much attention to ejaculation time, so that the process of sexual intercourse is not satisfactory, and over time it will even cause sexual neurasthenia.

To deliver without revealing the law:

That is, when a man is in the process of sexual intercourse, when the most exciting part of close sex is about to thank the essence, he suddenly artificially controls the essence or terminates the sexual intercourse immediately. As far as we know, a small amount of sperm has entered the female vagina before thanking sperm, so this method is also difficult to achieve the effect of contraception. In addition, long-term use of this method to have sex, it is easy to cause male impotence, abnormal ejaculation (such as poor or painful ejaculation, or even can not ejaculate), frequent ejaculation, induced aseptic prostatitis and other diseases. In addition, the law is also difficult to be mastered "just right" by the man.

Vaginal lavage:

Some couples do not have contraception when they have sex, and then lavage their vaginas after sex, thinking that this can be used for contraception. In fact, this method is also not safe, because after the penis ejaculates in the vagina, countless sperm will quickly swim to the uterus, and lavage can not flush all the sperm out of the vaginal orifice.

Female urination after sexual intercourse:

Vagina and urethra are two different tubes, female vaginal orifice is larger huge ass , located between urethra and anus, it is impossible to urinate sperm out of the vaginal orifice to achieve the purpose of contraception.
