How to Use Condoms Correctly: 10 Common Mistakes to Avoid

Condoms are one of the most effective tools for preventing both pregnancy and sexually transmitted infections (STIs)—but only when used correctly. With perfect use, condoms are 98% effective at preventing pregnancy. However, with typical real-world use, that effectiveness drops to around 85% . The difference?

Research analyzing 50 studies across 14 countries has identified a range of common mistakes that compromise condom effectiveness . The good news is that these errors are entirely avoidable. Here are the 10 most common condom mistakes—and how to fix them.

Mistake #1: Putting the Condom On Too Late

The Numbers: Between 17.1% and 51.1% of people wait until intercourse has already begun before putting on a condom .

Why It’s a Problem: Many people believe that withdrawal before ejaculation is enough to prevent pregnancy and STIs. This is dangerously false. During sexual arousal—well before ejaculation—a clear fluid called pre-ejaculate (pre-cum) can be released from the penis. This fluid can contain both sperm and STI-causing viruses . If the penis enters the vagina, mouth, or anus without a condom, transmission can occur even if ejaculation never happens.

The Fix: Put the condom on before any genital contact. As one health expert notes, “The penis should not come in contact with the vulva or vagina prior to placement of the condom” . Make putting on the condom part of foreplay—it can be a sensual, intimate moment rather than an interruption.

Mistake #2: Taking the Condom Off Too Early

The Numbers: Between 13.6% and 44.7% of people remove the condom before intercourse is fully complete .

Why It’s a Problem: Ejaculation isn’t the only moment when fluids are exchanged. If you remove the condom while the penis is still inside your partner, you risk exposure to pre-ejaculate and any STIs present. Additionally, nearly 31% of men and 27% of women report withdrawing too late, after the penis has already begun to soften, which can cause the condom to slip off inside the partner .

The Fix: After ejaculation and before the penis softens, grip the rim of the condom and withdraw from your partner . Hold the condom in place as you pull out to prevent any semen from spilling.

Mistake #3: Failing to Leave Space at the Tip

The Numbers: Between 24.3% and 45.7% of people don’t leave enough space for semen collection .

Why It’s a Problem: If there’s no space at the tip of the condom, semen has nowhere to go during ejaculation. The pressure can cause the condom to break or burst . This is one of the most common causes of condom failure.

The Fix: Pinch the tip of the condom before rolling it on. For condoms with a reservoir tip, squeeze it to remove air. For condoms without a reservoir, pinch the tip enough to leave about half an inch of space for semen to collect . Hold that pinched tip with one hand while unrolling the condom with the other.

Mistake #4: Not Removing Air from the Tip

The Numbers: Nearly half of women (48.1%) and 41.6% of men don’t squeeze air from the tip before use .

Why It’s a Problem: Trapped air inside the condom creates pressure points that can lead to breakage during sex . Think of it like an air bubble in a balloon—when pressure is applied, it’s the weakest point.

The Fix: Always squeeze the air out. Place the condom on the tip of the erect penis and use your thumb and forefinger to gently pinch the reservoir tip, expelling any air . Continue holding the tip as you roll the condom down to the base.

Mistake #5: Putting the Condom on Inside Out

The Numbers: Between 4% and 30.4% of people have started rolling a condom on inside out—and some continue using it that way .

Why It’s a Problem: If you start rolling a condom the wrong way and it won’t unroll easily, do not flip it over and continue. The outside of the condom will have already been exposed to the penis, meaning pre-ejaculate may be on the outer surface . This defeats the purpose of using a condom for protection.

The Fix: If it doesn’t unroll smoothly, throw it away and start fresh with a new condom . The condom is designed to unroll in one direction only. Practice a few times alone so you know which way it goes before you’re in the heat of the moment.

Mistake #6: Using the Wrong Lubricant (or None at All)

The Numbers: Between 16% and 25.8% of people use condoms without lubrication, and 3.2% of women and 4.7% of men use oil-based lubricants with latex condoms .

Why It’s a Problem: Without adequate lubrication, friction increases the risk of condom breakage . More critically, oil-based lubricants—such as petroleum jelly (Vaseline), baby oil, coconut oil, mineral oil, or lotions—can degrade latex in as little as 60 seconds, significantly weakening the condom .

The Fix: Use only water-based or silicone-based lubricants with latex condoms . Water-based lubes are safe with all condom types, easy to clean up, and won’t compromise the condom’s integrity. If you’re unsure, check the label—water-based lubes will clearly state they are compatible with condoms.

Mistake #7: Opening the Wrapper with Sharp Objects

The Numbers: Between 2.1% and 11.2% of people open condom packets with scissors, teeth, fingernails, or other sharp objects .

Why It’s a Problem: “If it’s sharp enough to rip the wrapper, it’s sharp enough to rip the condom” . Microscopic tears may not be visible but can compromise the condom’s integrity, leading to breakage during use.

The Fix: Open the wrapper with your hands. Feel for the condom inside the wrapper and push it to one side before tearing open gently . Always use clean hands and be careful with long fingernails or jewelry that could snag the condom.

Mistake #8: Not Checking for Damage or Expiration

The Numbers: A staggering 82.7% of women and 74.5% of men fail to check condoms for damage before use .

Why It’s a Problem: Condoms expire, and they can be damaged by improper storage. An expired condom is more likely to break—its material has degraded and lost elasticity . Condoms stored in hot places (like car glove compartments) or wallets for extended periods can also be compromised .

The Fix: Always check three things before use:

1. The expiration date—if it’s passed, discard the condom 
2. The wrapper—look for signs of wear, holes, or tears
3. The condom itself—after opening, check for brittleness, stickiness, or discoloration 

Mistake #9: Not Unrolling the Condom Fully

The Numbers: 11.2% of women and 8.8% of men have started intercourse before the condom was unrolled all the way down the penis .

Why It’s a Problem: A condom that’s only partially unrolled is more likely to slip off during sex . It also provides incomplete coverage, leaving the base of the penis exposed to potential fluid exchange.

The Fix: Unroll the condom all the way to the base of the penis . The condom should cover the entire shaft, from tip to base, before any penetration occurs.

Mistake #10: Reusing Condoms or Using Multiple at Once

The Numbers: Between 1.4% and 3.3% of people admit to reusing condoms .

Why It’s a Problem: Condoms are single-use only. Reusing a condom is not only unhygienic but also ineffective—the material has already been stretched and weakened. Using two condoms at once (double bagging) is also a bad idea; friction between the two condoms actually increases the risk of breakage .

The Fix: Use one new condom for each act of sex. If you’re switching between vaginal, anal, and oral sex, use a new condom for each type of penetration . This prevents bacterial transfer and ensures maximum protection.

Bonus Mistakes to Avoid

Quick Reference: How to Use a Condom Correctly

The Bottom Line

Condoms are one of the most effective tools we have for sexual health—but they only work when used correctly. As research shows, user error is the primary cause of condom failure, not manufacturing defects . The good news is that every mistake on this list is completely avoidable.

With a little practice and attention to detail, you can ensure that your condoms provide the maximum protection they’re designed to offer. Keep condoms accessible, check them before use, put them on early, and use them consistently.

Remember: The best condom is the one you use correctly every time.
