Nowadays, the pace of life is fast, especially for women who are extremely busy with work. Pregnancy can affect their work, so they will adopt methods of contraception. Using condoms is a more reliable method of contraception, but it is necessary to understand the front and back of condoms during use in order to be more comfortable to use. So, how to distinguish between the front and back of condoms?
How to distinguish between positive and negative condoms
1. It is not very reliable to distinguish between positive and negative based on whether the condom is lubricated, because when tearing open the condom, the hands often come into contact with lubricating oil, making it difficult to distinguish whether the condom has more or less oil on that side. Moreover, some condoms do not have much oil, so it is not reliable to distinguish between positive and negative based on whether there is oil.
2. A sleeve with protrusions and threads, if the sleeve head has protrusions and threads, it is easier to distinguish between the front and back, with protrusions and threads facing outward.
3. Condoms should not be directly placed on the penis because after erection, semen is secreted from the urethral opening. If it is reversed and then turned over, the sticky semen will be directly directed towards the female uterus, making it easy to be transported into the uterus and potentially leading to pregnancy.
Precautions for using condoms
1. Condoms can only be used once, and used condoms should be wrapped in tissue paper and placed in the trash can.
2. Condoms are made of rubber, but some people are allergic to rubber. Latex allergy sufferers should avoid using condoms as they can easily cause illness.
3. Condoms should be stored in a cool and shady place, as overheating or undercooling can cause them to rupture.
These are the knowledge that should be understood when using condoms, especially for some female friends. If effective contraception cannot be used, the harm to the body is also considerable. Therefore, women must pay attention to their health and actively use contraception to avoid this situation. Only at the appropriate time for preparing for pregnancy can they avoid taking contraceptive measures.
