Using a male (external) condom correctly every time brings its effectiveness to 98% against pregnancy over a full year. With typical use, which accounts for occasional mistakes, that number drops to about 87%. The gap between those two figures comes down to technique, and the technique is straightforward once you know it.
Before You Open the Package
Check the expiration date printed on the wrapper. Condoms degrade over time, and an expired one is more likely to break. While you’re at it, feel the package for an air cushion when you squeeze it gently. If there’s no air bubble, the seal may be compromised and the condom inside could be dried out or weakened.
Tear the wrapper open at a corner or along the serrated edge using your fingers. Don’t use scissors, your teeth, or anything sharp. A tiny nick in the latex is invisible but enough to cause a tear during use. Push the condom away from the edge you’re tearing so the wrapper does the work without catching the material.
Putting It On
The condom goes on after the penis is fully erect and before any genital contact with a partner. Pre-ejaculate fluid can contain sperm and transmit infections, so waiting until the last moment defeats the purpose.
Place the condom on the head of the penis with the rolled rim facing outward (it should look like a small hat, not an inverted cup). If you accidentally place it inside out, don’t flip it over. Discard it and use a new one, since the outside may already have pre-ejaculate on it.
Pinch the tip of the condom (the reservoir) between your thumb and forefinger to squeeze out trapped air. This step matters more than people realize. Air left in the tip creates a weak point that can burst under friction. While still pinching the tip, use your other hand to unroll the condom all the way down to the base of the penis. It should unroll smoothly. If it resists or feels tight, you may need a different size.
During Sex
If things start to feel dry, add lubricant to the outside of the condom. Friction without enough lubrication is one of the most common reasons condoms break. Water-based and silicone-based lubricants are safe with every type of condom. Oil-based products, including lotion, Vaseline, coconut oil, and cooking oils, will weaken latex and cause it to tear. If you’re using a polyurethane or lambskin condom, oil-based lubricants are fine, but for latex (which is what most condoms are made of), stick to water or silicone.
Periodically check that the condom hasn’t slipped upward. If it’s bunching near the tip instead of sitting at the base, it may be too large. If it rolls up partway during sex, hold the rim at the base and smooth it back down before continuing.
Never use two condoms at once. Wearing two male condoms (sometimes called “double bagging”) creates friction between the layers and makes both more likely to break. The same applies to pairing a male condom with an internal (female) condom.
Taking It Off
Withdraw soon after ejaculation, while the penis is still firm. As the erection fades, the condom loosens, and semen can leak around the rim or the condom can slip off entirely inside your partner. Hold the condom at the base, gripping the rim against the skin, as you pull out.
Once you’ve withdrawn, slide the condom off gently. Don’t tug or snap it, which can cause it to tear and spill. Tie the open end in a knot to contain the contents, wrap it in tissue, and throw it in the trash. Condoms should never be flushed. They don’t break down in water and will clog plumbing.
Use a new condom for every act of intercourse, including if you switch between vaginal, anal, and oral sex during the same session.
Getting the Right Fit
Condom sizes typically range from about 170 to 220 mm (6.7 to 8.7 inches) in length and 40 to 60 mm (1.6 to 2.4 inches) in flat width. A condom that’s too tight is more likely to break. One that’s too loose is more likely to slip off. Both scenarios also make sex less comfortable, which makes people less likely to use condoms consistently.
If a standard condom leaves a tight ring mark at the base or feels like it’s squeezing, try a larger size. If it slides around or bunches up, try a snugger fit. Most brands now carry at least three size options, and specialty brands offer a wider range. Getting the fit right is one of the simplest things you can do to reduce breakage and slippage.
Choosing a Material
Latex condoms are the most widely available and the most studied. They offer strong protection against both pregnancy and sexually transmitted infections. Most people use latex without issue.
If you have a latex allergy, polyurethane and polyisoprene condoms are the main alternatives. Both protect against STIs and pregnancy, though they tend to be slightly more prone to breakage than latex. Polyurethane transfers heat better, which some people prefer for sensation. Polyisoprene stretches more like latex and fits similarly.
Lambskin (natural membrane) condoms are a third option, but they have microscopic pores large enough for viruses to pass through. They prevent pregnancy effectively but do not reliably block STIs, including HIV. If STI protection matters to you, lambskin is not a substitute for latex or synthetic condoms.
Storage and Shelf Life
Where you keep your condoms affects whether they work. Heat, cold, and friction all degrade the material. A condom stored in a wallet gets bent repeatedly, pressed by body heat, and worn down by friction every time you sit or move. The same goes for glove compartments, which reach extreme temperatures in summer and winter. Even brief exposure to high heat or freezing cold can make a condom brittle, and bringing it back to room temperature doesn’t reverse the damage.
Store condoms in a cool, dry place at room temperature, like a bedside drawer or a bag pocket you don’t sit on. If a condom feels sticky, stiff, or brittle when you open it, throw it away and use a fresh one. Replace condoms as they approach their expiration date rather than waiting until they pass it.
What Condoms Do and Don’t Protect Against
Consistent, correct condom use reduces the risk of HIV, gonorrhea, chlamydia, and trichomoniasis. These infections spread through bodily fluids, and a condom creates an effective barrier.
Protection is less complete for infections that spread through skin-to-skin contact, including herpes, syphilis, and HPV. These can be transmitted by contact with sores, ulcers, or infected skin in areas the condom doesn’t cover, like the surrounding groin, inner thighs, or scrotum. A condom still helps when the infection is in an area it covers, but it can’t eliminate risk from exposed skin nearby.
Why Experience Matters
Research from the Guttmacher Institute found that people with fewer than five successful experiences using condoms were roughly 6.5 times more likely to have one break compared to those with more than 30 problem-free uses. Breakage and slippage rates dropped significantly as people gained familiarity with the method. This isn’t because condoms are unreliable. It’s because small technique details, like pinching the tip, using enough lube, and withdrawing promptly, become second nature with practice. If you’ve had a condom break or slip before, it doesn’t mean condoms don’t work for you. It usually means one of these steps needs attention.
