Putting on a condom correctly takes about 10 seconds once you know the steps, but small mistakes can seriously reduce its effectiveness. Used perfectly every time, condoms are 98% effective at preventing pregnancy. With typical use (which includes common errors), that drops to 82%, meaning roughly 1 in 5 women whose partners use condoms will get pregnant over a year. The difference between those two numbers comes down to technique.
Step-by-Step Application
Start by checking the expiration date on the wrapper. Condoms degrade over time, and an expired one is far more likely to tear. Tear the wrapper open along one edge, being careful not to use your teeth or scissors, which can nick the condom itself. Push the condom to one side of the packet before tearing so you don’t accidentally cut through it.
Place the condom on the head of the erect penis with the rolled rim facing outward (it should look like a small hat, with the rim rolling down easily). If you put it on inside out, the condom won’t unroll smoothly. Don’t flip it around and reuse it if this happens, because pre-ejaculate may already be on the tip. Use a new one.
Pinch the tip of the condom with your thumb and forefinger to squeeze the air out. This creates a small reservoir for semen and prevents an air pocket from forming, which is one of the most common causes of breakage. While still pinching the tip, use your other hand to unroll the condom all the way down to the base of the penis. If it won’t unroll easily, it’s probably inside out or the wrong size.
Getting the Right Size
A condom that’s too tight is uncomfortable and more likely to tear. One that’s too loose can slip off during sex or leave gaps that let semen leak out. Fit matters more than most people realize.
To find your size, measure while fully erect. For length, measure from the base to the tip along the top side. For girth, wrap a flexible measuring tape (or a piece of string you can hold against a ruler) snugly around the thickest part of the shaft, usually just below the head. Girth is the more important measurement for choosing the right condom width. To convert girth to the “nominal width” listed on condom packaging, divide your girth by 3.14. So a 5-inch girth means you’d look for a condom with a nominal width around 1.6 inches.
Standard condoms fit most people, but snug-fit and larger options exist for a reason. If you’ve experienced slipping or discomfort, sizing is likely the issue.
Choosing a Condom Material
Latex condoms make up about 80% of the U.S. market and are the most tested, most affordable, and most widely available option. They stretch well and have the lowest breakage rates. For most people, latex is the default choice.
If you or your partner has a latex allergy (roughly 4% of people do), polyisoprene condoms feel similar to latex and offer comparable protection. They have a snug, form-fitting feel. Polyurethane condoms are thinner and transfer heat better, which some people prefer for sensation. However, they’re less stretchy and about five times more likely to tear or break compared to latex. They also tend to fit more loosely, increasing the chance of slippage. They cost more, too.
Natural lambskin condoms are effective for pregnancy prevention but are porous enough to allow viruses through. They are not approved for STI prevention.
Using the Right Lubricant
Lubricant reduces friction, which makes sex more comfortable and significantly lowers the chance of the condom tearing. But the type of lube you use matters a lot depending on your condom material.
With latex or polyisoprene condoms, only use water-based or silicone-based lubricants. Water-based lubes are the safest all-purpose option: they’re non-irritating and won’t damage latex. Silicone-based lubes last longer and are also safe with all condom types, including latex and polyurethane.
Oil-based products, including massage oil, coconut oil, petroleum jelly, and many hand lotions, break down latex. This degradation weakens the condom and can cause it to fail. If you’re using polyurethane condoms, oil-based lubricants won’t damage the material, but oil-based lubes can still leave a coating inside the body that promotes bacterial infections, so water-based or silicone-based remains the better choice regardless.
Removal and Disposal
Withdraw while the penis is still erect. This is important: as the penis softens, the condom loosens and can slip off, potentially spilling semen. While pulling out, hold the base of the condom against the penis so it stays in place.
Slide the condom off carefully, keeping the open end pointed up to avoid spilling. Tie it off if you’d like, wrap it in tissue, and throw it in the trash. Don’t flush condoms. They don’t break down in water and can clog plumbing. Never reuse a condom, even if it appears undamaged.
Storage Tips That Protect the Condom
Heat, sunlight, and friction all degrade condoms before you ever open the wrapper. Store them in a cool, dry place away from direct sunlight. Long-term storage temperatures should stay below 86°F (30°C), and even short-term exposure above 104°F (40°C) can compromise the material.
This means your wallet, car glove compartment, and back pocket are all poor choices for storage. A wallet subjects the condom to body heat and constant friction from sitting. A car interior can easily exceed 120°F in summer. A bedside drawer or a cool, dry spot in your bag works much better. Check expiration dates periodically and replace any condoms that have been stored in questionable conditions.
What to Do if a Condom Breaks
If a condom tears or slips off during sex, stop immediately. The sooner you act, the more options you have.
For pregnancy prevention, emergency contraception is most effective within 72 hours (three days), though some options can be taken up to five days after. Over-the-counter options are available at most pharmacies without a prescription. Effectiveness drops with every hour of delay, so don’t wait to see what happens.
If there’s a concern about HIV exposure, preventive treatment called post-exposure prophylaxis (PEP) can reduce the risk of infection, but it must be started within 72 hours. This requires a prescription, so contact a healthcare provider, urgent care clinic, or sexual health clinic right away. For other STIs, testing is typically done a few weeks after exposure, since infections take time to show up on tests.
Common Mistakes to Avoid
- Skipping the pinch. Not squeezing air out of the tip is one of the most frequent errors. Trapped air creates pressure that can cause the condom to burst.
- Putting it on late. The condom should go on before any genital contact, not just before ejaculation. Pre-ejaculate can contain sperm and transmit infections.
- Using the wrong lube. Oil-based products with latex condoms are a recipe for breakage. Check the label.
- Opening the wrapper carelessly. Teeth, long nails, and scissors can create tiny tears you won’t notice until it’s too late.
- Not checking the direction first. If the condom doesn’t unroll easily, it’s inside out. Discard it and start fresh rather than flipping it over.
- Waiting too long to withdraw. Pulling out after the penis has gone soft allows the condom to slip off inside your partner.
