Although condoms help couples prevent pregnancy, some condoms are harmful to the body. Men must stay away from them. Let us learn about them together. I hope it will be helpful to everyone.

Never use the four types of condoms

1. Glow-in-the-dark condoms

Some condoms on the market are luminous. These condoms contain a coating called phosphorus. Although it can increase the interest of sexual intercourse, phosphorus is very allergenic. Therefore, I suggest you be cautious and not blindly pursue novelty.

2. Condoms with too thick latex particles

There are also some condoms with particles or spiral protrusions, which can effectively increase the friction with the vagina. It is very effective in pleasing women, but in comparison, such condoms are more prone to cracks.

Therefore, the particle size of some qualified products will be limited. For safety reasons, it is better not to choose condoms with too coarse particles.

3. Scented condoms

Nowadays, there are many strawberry, chocolate and other flavored condoms on the market, which are often prone to inflammation of women's vagina when used. Therefore, when choosing to use these products, pay close attention to whether there are abnormal vaginal secretions in women's vaginas. situation, try to minimize its use.

4. Medicinal condoms

This type of condom has nonoxynol ether spermicide, anti-inflammatory drugs, sexual excitement delaying agents, erection aids and other drugs added to the condom. Although it has a certain effect, regular use will definitely affect men and even men. The female reproductive system is best not to be tried lightly.

What should you pay attention to when using condoms

1. Inspection before use

Before using a condom, perform a basic inspection of the condom. You should check the production date and expiry date before use. Expired condoms have deteriorated and are easy to break and should not be used. Many people fail to check the validity period of condoms before use, causing condoms to break during use, resulting in unintended pregnancy.

2. Save and place

There are also some precautions to be taken when storing condoms. They do not just need to be placed in a hidden place. Condoms must be stored in a cool, dry environment and away from acids, alkalis, and oils. If it becomes sticky or brittle after exposure to the above conditions, it should not be used even within the shelf life.

3. Select model

Everyone's penis size and length are different, so choose condoms of different sizes. Condoms come in different specifications, and the appropriate model should be selected according to the size of the penis when it is erect. Otherwise, if it is too tight and easy to break, if it is too loose and easy to slip, it will affect the effectiveness of use. Generally speaking, Asians often use medium-sized condoms.

4. Do not expand in advance

When using a condom, do not unfold the condom, but unfold it from the glans to the head of the erect penis. However, many people unfold the condom in advance, and when the penis is erect, they cannot put on the condom smoothly, and air will be trapped inside.

Not only should you choose condoms carefully, but you should also pay more attention when using them. I hope everyone can pay more attention to contraception without affecting your health.
