Sexual life is a very important part for most couples in a relationship. So condom also plays a very important role in sexual life. It is also a tool that every boy will use. It is used not only for contraception, but also to protect both parties and to avoid infection. According to data, a man will use about 2,920 pcs condoms from the age of 20 to 29; about 1,278 pcs condoms from the age of 30 to 39; and about 730 pcs condoms from the age of 40 to 49 according to this formula...... According to this data, a man will use 5,731 pcs condoms in his lifetime. However, for many people: after wearing so many condoms, maybe they have never worn them correctly once. So whether you are a new driver or an old driver, will condoms really be effective in preventing pregnancy after using them for so long? Do you really understand condoms?
Condoms material and their advantages&disadvantages
|
Material |
Natural rubber latex |
Polyurethane |
|
Advantages |
Low cost; simple process; wide application range |
the workmanship is good; the thinness is good; the material is safe and non-allergenic |
|
Disadvantages |
Specific groups of people are allergic; the thickness is limited and cannot be too thin; has latex smell |
High price; relatively poor elasticity; too thin; relatively higher breakage rate |
The most common materials on the market are natural rubber latex and polyurethane:
Latex: Most condoms are made of natural latex, which is low-cost and widely used. However, about 8% of the population is allergic to latex, so please use it with caution.
Polyurethane: Suitable for people who are allergic to latex. Condoms made of polyurethane have strong toughness and thermal conductivity, but are not as elastic as latex. However, they can be made ultra-thin at 0.03mm to increase the pleasure of users and will not cause allergies.
In addition to the two main materials mentioned above, there are also some other less common materials used to manufacture condoms, such as polyisoprene, animal intestinal membranes(usually sheep intestinal membranes), polyvinyl alcohol, etc. These materials each have their own characteristics, for example, Polyisoprene condoms have high elasticity, good wear resistance, acid alkali corrosion resistance; but heat resistance, poor thermal conductivity, difficulty in mechanical processing. Condoms made from animal intestinal membranes have better thermal conductivity and tactile sensation, but can not be used with oily lubricants; Polyvinyl alcohol condoms are thinner and more transparent, but have a shorter lifespan.
Lubricant in the condoms
|
Material |
Silicon oil |
Hyaluronic acid |
|
Advantages |
Good lubrication effect, long-lasting lubrication and low cost |
Soluble in water, easy to clean, good hydration effect, non-greasy, no residue |
|
Disadvantages |
Insoluble in water, difficult to clean, easy to leave residue, strong greasy feeling |
High price, lubrication duration is shorter than silicone oil |
Silicone oil: Silicone oil has good lubrication effect and long-lasting lubrication. Because it is insoluble in water, the lubrication effect remains even if it lasts for dozens of minutes; also because it is insoluble in water, it will become more difficult to clean up afterwards, and there will still be residues even after careful cleaning. Think about whether there is still a trace of greasy feeling on your body after you clean it before?
Hyaluronic acid: As a water based lubricant, hyaluronic acid is soluble in water. This is very different from silicone oil when cleaning. It will be cleaned up with water and there will be no greasy feeling at all. In addition, during sex, due to the characteristics of water soluble lubricant, it will have a special water-retaining effect on the vagina, which is very friendly to women. Since hyaluronic acid is soluble in water, the lubrication duration of the lubricant is not as good as silicone oil. If the man is very strong and can easily last for dozens of minutes or an hour, he may need to change the condom halfway.

Large(L) condom: 55mm nominal width with 35mm opening diameter
Condoms of different brands are classified in the same size. People in different regions have different physical characteristics, so condoms also have different sizes. If feel that it is too tight or too loose after using it once, people should use a thin thread to wrap around the middle of the penis after it is fully erected, and then measure the length of the thread. The result is the penis circumference value, and then divide it by 2. Then, based on this calculation result, consult and buy condoms of the right size.
Condoms thickness
The thickness of condoms commonly found on the market is
Normal condom: 0.055mm to 0.065mm
Thin condom: 0.04mm to 0.055mm
Ultra thin: 0.02mm to 0.03mm
Latex condom is soft and elastic, with good thermal conductivity, and has always been the first choice of the public. However, due to the characteristics of the material, it can not achieve ultra thin effects, with the thinnest being 0.045mm. The biggest feature of polyurethane is its thinness, which can easily achieve a thinness that latex can not achieve, but it feels like plastic and has a bad touch.
Is thick condom safe? In theory, that's how it is said, but the key is quality, thinner and closer to reality. The thicker the condom, the lower the sensitivity of the male penis during sexual activity, and the poorer the sexual pleasure naturally; On the contrary, the thinner the condom, the higher the sensitivity of the penis during sexual activity, and the stronger the sexual pleasure naturally. For men with normal erectile function, wearing a certain thickness of condom can delay the latency period of ejaculation, which means it can delay the occurrence of ejaculation and prolong sexual intercourse time.
Classification of the condoms
Ordinary condom: used by men, the most common condom
Oral condom: contain edible lubricants, various flavors
Finger condom: used on fingers, hygienic and safe
Female condom: used by women, with a higher degree of safety protection
Type of ordinary condoms: smooth/plain/classic, dotted, ribbed, dotted+ribbed, ultra-thin, delay, flavor, color, ice feeling, hot feeling, etc.
When it comes to the issue of condom types, many people are starting to wonder why there are so many types? Ultra thin is preferred for those with longer personal time. Dotted, ribbed, dotted+ribbed can bring different happiness to the other party and increase the passenger experience while driving. There are three types of delay: the first is physical delay; and the other is constrained, which is particularly tight and can be in a tight state, reducing sensitivity; the third is drug delay, condoms contain liquid components (lidocaine
/benzocaine) that can prolong the duration, paralyzing the penis and increasing its duration. In terms of flavor, it mainly masks the smell of lubricating oil or latex, vanilla, strawberry, orange, not the taste, but the smell. Of course, edible flavor is also OK. There are two types of sensations, ice feeling and hot feeling. The female condom is first inserted into the female partner, and the man does not need to carry it himself. But the experience is not very good, so it is sold very little on the market.
Although oral condom is not popular, its effectiveness has been increasingly recognized by more and more people. Because if a ordinary condom is used during oral sex, not only can the lubrication of the condom not be maintained, but the tongue will also become numb; Moreover, its taste is disgusting. In this case, a condom for oral sex is needed. In addition to various flavors, oral condom is also made of some special materials, so that the bitterness of rubber latex will not be felt during oral sex. More humanized is that users can choose any flavor they like (such as apple, chocolate, lemon, etc.).
Why do we need to wear oral condom during sex? 1.Prevent oral cancer. A study has found that 64% of cancers in the mouth, head, and neck are caused by HPV, which is typically transmitted through oral sex. 2.Prevent AIDS. According to the most authoritative research on oral transmission of HIV risk so far, the risk of oral transmission of HIV is higher than that expected by experts. 3.Increase interest. Oral condom will add strawberry, banana, grape, chocolate and other edible essence. It tastes in multiple flavors, adding more interest to oral sex.
Finger condom is natural latex condom that provides protection during sexual activity. When used, it is worn on the fingers and enter the female body for stimulation, avoiding direct contact between the fingers and the genital organs and mucous membranes, avoiding bacterial and nail damage, providing sufficient lubrication protection, and being clean and safe. The main function is to ensure the health and hygiene of sexual behavior, avoid the transmission and infection of sexually transmitted diseases, and prevent damage to fragile mucosal areas caused by hard parts of the hands. Attention, in order to protect women's physical health, please choose a medical grade sex finger condom. In addition to conventional latex materials, there are also finger condom made of silicone or polyurethane. Silicone finger condom typically has a textured and unrestrained surface design, which can provide additional stimulation and can be reused after cleaning.
How to use condoms and precautions
1 Before each sexual intercourse, a new condom must be used.
2 Carefully tear open the individually sealed packaging bag, and avoid using sharp tools such as scissors.
3 Pinch the front end of the condom with your fingers, squeeze out the air, and then put it on the erect penis.
4 Keep space at the front end of the condom.
5 Make sure the condom covers the entire penis.
6 If necessary, use a water based lubricant. Oil based lubricant (such as glycerin, white vaseline) will cause the condom to harden and rupture.
7 After ejaculation, while the penis is still erect, hold the edge of the condom tightly to pull the penis out.
8 Do not put condoms in your pockets or near other heat sources. Long term proximity to heat sources will cause condom aging.
9 The best time to wear a condom is after the penis is erect and before the penis comes into contact with the genitals or anus.
10 When using a condom, turn up the foreskin of the penis. This can increase flexibility and reduce the risk of condom rupture during sexual intercourse.
11 If the penis is in the penis when it is used or placed. If the condom is not erect or is worn in the wrong direction during installation, please use a new one.
12 Do not use expired condom. Expired condom is likely to break during sexual intercourse.
13 After ejaculation, even if the penis is still erect, please immediately remove the penis from the vagina or anal to avoid unnecessary risks.
14 When removing the condom, press the base of the condom to prevent it from falling off.
15 Inexperienced users should practice using condom in a brightly lit place to ensure that it can be installed correctly before sexual intercourse.
16 Condom has different specifications. The appropriate size should be selected according to the size of the penis when erect. If it is too large, it will fall off in the vagina; If it is too small, it will be squeezed and semen will flow into the vagina.
17 Condoms must be stored in a cool, dry environment that is not exposed to acids, alkalis and oils. If it becomes sticky and brittle after contact with the above conditions, it should not be used again even within the shelf life.
18 Before putting it on the glans, the small air bag at the top of the condom for storing semen should be pinched to prevent the air in the air bag from expanding when heated, causing semen to overflow to the base of the penis during ejaculation.
19 The condom should not be unfolded in advance, but should be unfolded from the glans part downward on the erect penis head.
20 If a condom is found to have a crack or slip during use, it is still unsafe to just replace the condom. Sexual intercourse should be stopped immediately and the genitals should be cleaned with disinfectant.
21 After ejaculation, press the bottom of the condom with your fingers before the penis becomes flaccid and pull it out together with the penis.
22 When removing the condom, do not let semen flow out, and do not let the vaginal secretions outside the condom touch the body. Each condom can only be used once, and the used condom should be put into a plastic bag and thrown into the trash can.
23 It is impossible for the fingers that remove the condom to not come into contact with semen and vaginal secretions at the same time. Therefore, you cannot touch the female organs with your hands after sexual intercourse. Must wash hands with soapy water under running water immediately.
Some common mistakes when using the condoms in the daily life
1 Wearing condoms halfway: according to statistics, about 17% to 51% of people said that they would not use condoms at the beginning of sexual life. In fact, men will have some secretions before ejaculation, which is a transparent mucus that may contain a considerable amount of sperm. If it happens to be during the ovulation period of women, it will greatly increase the chance of pregnancy and increase the possibility of contracting sexually transmitted diseases.
2 Take it off in advance: about 13% to 44.7% of people admit that they take off the condom during sex. This operation is no different from not wearing it, and I find it difficult to understand the meaning of their use of condoms.
3 Remove air: there is a bulge similar to a water drop shape at the front of the condom, which is the sperm vesicle. According to statistics, 41.6% of men and 48.1% of women said that they did not know that they should squeeze out the air in the sperm vesicle of the condom before using it. If the air in the sperm vesicle is not squeezed out, the possibility of condom rupture will increase. The correct way is to gently pinch it with fingers to remove the air inside.
4. No inspection before use: In our daily habits, when using condoms, everyone is eager to put them on the penis, and the environment may be dim. According to statistics, up to 74.5% of men and 82.7% of women do not have the habit of checking whether the condoms are damaged or have holes in advance. In fact, many accidents are caused by this.
5 Improper storage: Legend has it that putting condoms in a wallet can ward off evil and attract wealth. When need it, at least there will be condoms as a spare, which is actually okay. But some people will put unopened condoms in direct sunlight or next to the heater. However, continuous high temperature will cause the condoms to deteriorate and damage, affecting their use. At the same time, be careful not to put them in a humid place, and do not put them together with camphor and medicines. It is best to store them in a dry, ventilated and light proof place.
6 Wear two condoms: A few men think that wearing two condoms can reduce sensitivity, prolong time, and make sex last longer. Or think that wearing two condoms can enhance protection. In fact, wearing two condoms at a time is worse than wearing one, and the friction between the latex of the two condoms is more likely to cause damage and rupture.
7 Contraception index as high as 100%?: Many obstetricians and gynecologists advocate double protection contraception, that is, women take oral contraceptives and men use condoms, because condoms have a contraceptive effect of about 97%, but not every women’s physique is suitable for contraceptives. It is recommended to consult a doctor before taking it.
8 Condom size is not important?: Men should not choose condoms larger than their own size, so as to avoid them falling off or breaking during sex. Men with large penises should not choose condoms that are too small, so as to avoid the penis becoming soft due to being too tight. It is recommended to choose the right size.
9 Pay attention to the front and back sides. If you wear it wrong, please change to the next one directly. Every time wear it wrong, turn it over and put it on again, but this is actually wrong! Because the prostate fluid secreted from the front of the penis may contain a little sperm. If you wear it on the back side after it is stained, you may still get pregnant! The correct way to wear it should be to put the edge of the condom on the outside and the edge down, and naturally push it to the whole root, and it can cover the root. If you wear it on the back side, you will feel a little stuck when you push it to the root. At this time, don't push it hard! You can't just change the side! You have to change a condom directly! Look carefully before wearing it!
10 Wear a condom when you are giving oral sex! ?Everyone must think it's strange! Isn't it because you don't want to get pregnant that you use your mouth to push it first, then why don't you enjoy the warm pleasure of the mouth and wear a condom? According to statistics, 10% of people use condoms during oral sex. Although it sounds strange, some infectious diseases can be transmitted through the oral cavity, and there is also the possibility of cross-infection of bacteria, so it is still necessary to wear condoms!
11 Wear it before it stands up: I met a stupid friend who wanted to watch her boyfriend blow up a balloon with his penis, so she put a condom on his penis before it stood up, and then watched his penis grow. It sounds ridiculous, right? And this is a completely wrong demonstration, because putting a condom on a penis that has not stood up will cause a lot of air around it. When it really stands up, the condom will be squeezed together with the air, making it more likely to break!
12 Use readily available lubricating oil: When using lubricant, remember to avoid coconut oil, lotion, massage oil and vaseline, because these products may decompose latex components of condoms and cause damage to condoms. Love requires the use of lubricant, and water soluble lubricant is sufficient. Do not be tempted by convenience or cheap prices and use something casually, as it may not be worth the loss.
13 A condom is used from head to toe: the correct method is to change the condom as soon as the position is changed. Many people change their location and posture in their sexual life. At this time, the penis wearing a condom will come out of the women body. The condom at this time is easy to absorb fungi and bacteria in the air. If they enter the women body again, it will damage the women's private health and lead to many women diseases.
14 The depth of the condom is too deep: many people do not know what the depth of the condom refers to. Here is an explanation: when wearing a condom, most people will bring it to the glans and stick it to the condom, leaving only the protruding part. At this time, it is easy to cause the urethral opening to stick to the condom due to erection and movement during the process. As a result, it is easy to affect the smoothness of ejaculation at the moment of ejaculation, causing a feeling of blockage and forming reflux. This situation is like opening the gate of a reservoir, which could have poured down, but was blocked by a wall in front, making it easy for the liquid to reflux. The more times this operation is performed, the less conducive it is to the release of local congestion and swelling, and it is also prone to affecting the prostate. So, it is recommended that everyone wear a condom not too close to the urethral opening and leave a little space for ejaculation as much as possible.
15 Condoms can block all sexually transmitted diseases: proper use of condoms can reduce the risk of HPV infection by 60-70%, thereby reducing the incidence of genital warts and cervical lesions. But HPV can still cause HPV infection in female external genitalia, anus and other parts of the body that are not protected by condoms. Proper use of condoms can reduce the risk of HIV transmission by about 80% and effectively reduce the risk of sexually transmitted diseases such as herpes simplex virus and syphilis.
16 Condoms can provide 100% contraception: unless there is sexual intercourse, there is currently no contraceptive method that can achieve 100% effective contraception. With the correct use of condoms, the effective contraception rate can reach up to 97%. Therefore, as a simple, efficient, and low side effect contraceptive method, condoms can be regarded as the preferred contraceptive method.
