Condoms are easy to use and have no side effects. But when using condoms, you must pay attention to using them correctly, otherwise they will not have a contraceptive effect.
How to wear a condom is already a familiar task for \”car gods\”, but for novices, there are many \”pitfalls\” on the way to put on a condom correctly. 
The correct way to use condoms
First, be careful not to tear the condom when opening the package, but be careful not to scratch the condom.
Second, before putting the condom on the glans, you should squeeze the small air bag at the top of the condom for storing semen. When wearing it, it should be on the head of the erect penis, and quickly expand downward from the glans. But before putting it on the penis, , do not expand it beforehand.
Third, continue to pinch the empty condom at the tip while unfolding the condom to the base of the penis.
Fourth, after ejaculation, when the penis is erect, pinch the mouth of the condom tightly and carefully withdraw the penis from the vagina.
When choosing a condom, you should check whether the model matches you. If it is too big, it will fall off easily, and if it is too small, it will break easily. 
How to remove the condom afterwards?
First, press the bottom of the condom with your hands immediately while the \”little brother\” is still erect, and then take it off after completely pulling it off to prevent semen from flowing out from the end;
Second, if there is leakage after taking out the condom, girls need to take birth control pills as soon as possible for contraception;
Third, you need to tie the end of the condom with a knot after use, and then throw it into the trash can to prevent semen from flowing around;
Fourth, clean it afterwards, which is better for your health.
