Putting on the Condom Too Late ：
Many people only think to put on a condom after sexual activity has begun, with this mistake occurring in 17.1%-51.1% of cases. In fact, a condom should be put on during foreplay to prevent direct contact between sexual organs, thereby reducing the risk of pregnancy and the transmission of sexually transmitted infections (STIs). Additionally, 13.6%-44.7% of people prematurely remove the condom before the end of sexual activity. Even if ejaculation has been completed, this can still lead to fertilization or disease transmission.
Unrolling the Condom Before Putting It On：
2.1%-25.3% of people unroll the condom completely before putting it on. This can damage the condom and make it difficult to wear correctly. The proper method is to place the condom on the head of the penis and then unroll it downwards.
Not Leaving Space for Semen：
24.3%-45.7% of people have encountered situations where there is no space or insufficient space in the condom’s reservoir tip, increasing the risk of condom breakage and pregnancy. The correct practice is to ensure that there is enough space at the tip of the condom to hold semen when putting it on.
Not Squeezing Air from the Tip of the Condom：
Approximately half of women and 41.6% of men do not squeeze air out of the tip of the condom during use, which increases the risk of the condom breaking. The correct procedure is to gently squeeze the tip of the condom with your fingers to remove the air before wearing it.
Putting the Condom on Inside Out：
4%-30.4% of people put the condom on inside out, which not only makes it uncomfortable for the wearer but also makes the condom more likely to slip off, reducing its effectiveness. The correct method is to ensure that the rolled edge is facing outwards when unrolling the condom.
Not Unrolling the Condom Completely：
11.2% of women and 8.8% of men only unroll the condom halfway, covering just part of the penis. This is very dangerous as it does not provide full protection and increases the risk of STI transmission. The condom should be fully unrolled to cover the entire penis.
Opening the Condom Package with Sharp Objects ：
2.1%-11.2% of people use sharp objects like knives or sharp fingernails to open condom packages, which can cause the latex to tear or develop holes, reducing its effectiveness. The correct approach is to gently tear open the package by hand, avoiding any tools that might damage the condom.
