Putting on a condom correctly takes about 10 seconds once you know the steps, and doing it right is the difference between 98% effectiveness and roughly 87% effectiveness at preventing pregnancy. The process is straightforward: check the condom, pinch the tip, roll it down. But the details matter more than most people realize, and skipping even one step is a common reason condoms break or slip off.
Check the Condom Before You Open It
Start by looking at the expiration date printed on the wrapper. If you can’t find one or can’t read it, throw it away and use a different one. Press down gently on the wrapper. You should feel a small air cushion inside, which tells you the seal hasn’t been punctured. If the wrapper feels flat or the foil looks damaged, the condom may already be compromised.
Storage matters too. Condoms degrade in heat above 104°F (40°C), so a condom that’s been sitting in a car glovebox, a back pocket, or a wallet for weeks may not be reliable. Keep them in a cool, dry place like a bedside drawer.
Step-by-Step Application
Open the wrapper carefully by tearing along the edge. Don’t use your teeth or scissors, both of which can nick the condom itself.
Before unrolling, check the direction. The rim should sit on the outside so the condom looks like a small hat with the rolled edge curling away from you. If you place it on the wrong way and it won’t unroll, don’t flip it over and reuse it. Pre-ejaculate fluid may already be on the outside, so toss it and start with a new one.
Pinch the tip of the condom between your thumb and finger. This removes trapped air and leaves a small reservoir at the top to collect semen. Air trapped in the tip is one of the most common causes of breakage.
Place the pinched tip on the head of the erect penis. If uncircumcised, pull the foreskin back first. Then roll the condom all the way down the shaft to the base with your other hand. It should feel snug but not painfully tight, and it shouldn’t bunch or slide around.
Put the condom on before any contact with a partner’s mouth, genitals, or anal area, not just before intercourse. Pre-ejaculate can transmit STIs and, in some cases, cause pregnancy.
Getting the Right Fit
Condom fit is one of the biggest factors in whether they stay on and stay intact. A condom that’s too tight is more likely to break. One that’s too loose is more likely to slip off. Girth (circumference) matters more than length for finding the right size.
To measure, wrap a flexible tape or a piece of string around the thickest part of the erect penis, usually near the middle of the shaft. Use these general guidelines:
- Snug fit: girth under 4.7 inches
- Regular fit: girth between 4.7 and 5.1 inches
- Large fit: girth between 5.1 and 6 inches
Once a condom is on, check for two things. If there’s a lot of extra material rolled up at the base, you likely need a snugger size. If there’s no rolled rim left at the base and the condom feels stretched, go up a size.
Using Lubricant Safely
Extra lubrication reduces friction, which lowers the chance of breakage and makes sex more comfortable. But the type of lube you use depends on the condom material.
Most condoms are latex. Oil-based products, including coconut oil, petroleum jelly, body lotion, and cooking oils, break down latex and significantly increase the chance of tearing. Stick with water-based or silicone-based lubricants for latex condoms. Apply lube to the outside of the condom after it’s on, not to the penis underneath (which can cause slipping).
If you’re using polyurethane, polyisoprene, or nitrile condoms, typically chosen by people with latex allergies, these materials are compatible with any type of lubricant, including oil-based options.
Removing the Condom
Withdrawal and removal are where many failures happen. Pull out while the penis is still erect. As you withdraw, hold the condom firmly against the base of the penis so it doesn’t slip off or spill. Once fully withdrawn, slide the condom off away from your partner, tie the open end to contain the contents, and throw it in the trash. Never flush condoms; they clog pipes. Never reuse a condom. Use a new one for each act of sex, including if you switch between vaginal, anal, or oral contact.
Why Condoms Fail
About one in three condom users reports a breakage or slippage incident over a 90-day period, according to research on adolescent males. The strongest predictor of failure is never having received instruction on correct use, which is exactly what proper technique prevents.
The most common mistakes that lead to breakage or slipping:
- Not pinching the tip: trapped air creates pressure that tears the latex during use
- Using oil-based products with latex: weakens the material within minutes
- Wrong size: too tight tears, too loose slides
- Putting it on late: applying mid-act after contact has already happened
- Using expired or improperly stored condoms: degraded material is less elastic and more brittle
- Opening the wrapper carelessly: fingernails, teeth, or sharp objects can create invisible tears
Choosing a Condom Material
Latex condoms are the most widely available, most affordable, and the most studied for effectiveness. They protect against both pregnancy and STIs, and they work with water-based and silicone-based lubricants.
Polyurethane, polyisoprene, and nitrile condoms are alternatives for people with latex allergies. They’re equally effective at preventing pregnancy and STIs, compatible with all lubricant types, and some people find they transmit sensation better than latex.
Lambskin (natural membrane) condoms are the exception. They have microscopic pores large enough for viruses to pass through, so while they prevent pregnancy, they do not protect against STIs. If STI prevention matters to you, avoid lambskin.
