Can condoms prevent diseases? Condoms can prevent diseases. Condoms have a certain preventive effect on sexually transmitted diseases, but it is impossible to completely prevent them, such as AIDS and gonorrhea. Moreover, some sexually transmitted diseases can also be transmitted through mucous membranes. If you want condoms to play the biggest role, you must use them correctly. The wearing method of condoms is as follows:
1. Please check the expiration date of the condom before use. Expired condoms are dry and easy to crack, so they are not suitable for use. Ensure that condoms are within the validity period, carefully tear open the individually sealed packaging bags and avoid using sharp tools such as scissors and teeth.
2. Open the condom and put it at the end of penis. If the condom cannot be unfolded due to the wrong condom, please remove it and replace it with a new one. Please don't reuse the inflated condom!
3. The residual air in the condom will cause the condom to rupture. In order to avoid the possibility of rupture, gently squeeze the air out of the small bag at the front end of the condom with your thumb and forefinger, and then put the condom on the erect penis to ensure that the curled part at the end of the condom is exposed. While squeezing the front end of the condom, gently stretch the condom with the other hand to cover the whole penis. Each condom can only be used once. Used condoms are wrapped in paper towels and put in the trash can.
