Sometimes Condoms have tiny holes in them that the factory didn't catch. Sometimes they are too thin and can break or get tiny holes without you realizing it during regular sex. Some people don't know how to use them properly. There are a million and one reasons that a man made product will not work properly. But all of these things bring down their average working time to 86% when used correctly. Your local Planned Parenthood has a lot of great statistics, and even they recommend using spermicide gel or some other BC method while using a condom.
"Of 100 women whose partners use condoms, about 15 will become pregnant during the first year of typical use.* Only two women will become pregnant with perfect use.** More protection against pregnancy is possible if condoms are used with a spermicide foam, cream, jelly, suppository, or film."
Handle condoms gently. Store them in a cool, dry place. Long exposure to air, heat, and light makes them more breakable. Do not stash them continually in a back pocket, wallet, or glove compartment.
Lubricate the inside and outside of the condom. (Many condoms are pre-lubricated.) Lubrication helps prevent rips and tears, and it increases sensitivity. Use water-based lubricants, such as K-Y jelly or AstroGlide, or silicone-based lubricants, such as Eros, with latex condoms. Oil-based lubricants like petroleum jelly, cold cream, butter, or mineral and vegetable oils damage latex.
