Will condoms leak?

Condoms can also cause leakage and are not 100% successful, so people must pay attention to protection when using them. If leakage is found, it is best not to use them, because this will not achieve a good contraceptive effect. You also need to choose a condom of appropriate thickness. If it is too thick, male friends will not be able to have a normal sexual life.

Condoms cannot completely protect against viruses

Traditional condoms have safety defects. While traditional natural latex condoms are effective in preventing pregnancy, they have a certain barrier effect on viruses, but they cannot effectively prevent viruses. Condoms can safely prevent pregnancy, but they are not guaranteed to prevent viruses.

The materials used in condom products on the market are mainly natural latex, whose natural cracks range from 5000 to 70000 nanometers, which is enough to prevent the human sperm head with a diameter of 5000 nanometers. However, the diameter of the HIV virus is only 120 nanometers, the diameter of the human papillomavirus is between 45 and 55 nanometers, and the diameter of the large spherical particles of the hepatitis B virus is 42 nanometers. The size of various viruses is much smaller than the natural cracks in natural latex. Even if condoms are used correctly, it is still possible to be infected with sexually transmitted diseases.

Choose the thickness of condoms appropriately

The thickness of the condom has a great impact on men's psychology. The thicker the condom, the less sensitive the male penis will be during sex.

There are three main types of condoms: ultra-thin, thin and regular. Among them, the thickness of the ultra-thin type is 0.03 mm, the thickness of the ordinary type is 0.04-0.06 mm, and the thin condom is between the two. A study in the United States showed that for every 0.01 mm decrease in thickness, men's comfort level will increase by 20%.

Ultra-thin condoms are not suitable for everyone. For men who ejaculate quickly, are older and have poor self-control, they should use thicker condoms or choose to use delayed-release condoms.

Thickened physical delay condoms and special delay condoms. The thickened physical delay condoms are based on the different sensitivity levels of men. They are locally thickened at the most sensitive parts of the male penis, such as the glans, coronal sulcus and frenulum. This provides a green, safe and non-toxic physical delay method for men with short duration. Special delayed-release condoms add a desensitizing ingredient commonly used in medicine, zocaine, to the lubricant, which can reduce the sensitivity of male sexual organs and thus prolong the duration of sexual intercourse.
