In an older study, 7.3 percent of the men surveyed said they had experienced a condom breaking over the course of a year. In other research, 29 percent of male appliers of condoms and 19 percent of female appliers reported experiencing at least one broken condom in the previous 3 months.
Of these, 402 men reported using 13,691 condoms for vaginal or anal intercourse; 7.3% reportedly broke during application or use and 4.4% slipped off.
The failure rate of condoms in couples which use them consistently and correctly is estimated to be about 3% during the first year of use. However, the true failure rate during that time period is estimated to be about 14%. This marked difference of failure rates reflects usage error.
Condoms can come off during sex if they're not the right size or not put on properly. Your boyfriend should pick the size and brand that fits most comfortably and snugly. When putting on the condom, roll it all the way down your boyfriend's erect penis, not just part of the way.
Condoms made from plastic (such as polyurethane condoms) protect against both pregnancy and STIs. Plastic condoms break more often than latex; using a water- or silicone-based lubricant can help prevent breakage. Condoms made from synthetic rubber (such as polyisoprene condoms) protect against both pregnancy and STIs.
Best for People with Penises
BareSkin external condoms are one of Trojan's bestsellers and for good reason. The latex external condoms are 50 percent thinner than the brand's Ribbed Ecstasy condom, giving them an even more sensitive and natural feeling.
Condoms may rip during use if they don't fit properly or if they are not put on correctly (such as not leaving enough room at the tip of the condom).
Condoms with spermicide
Some condoms come with spermicide on them. You should avoid using this type, or using spermicide as a lubricant, as it does not protect against STIs and may increase your risk of infection.
No one type of condom is necessarily better than another. Both Durex and Trojan offer a wide variety of safe and effective condoms that are reliable and well-tested.
It's conclusion? "Conclusion: Breakage and slippage rates were low for both condom types. There is no evidence from the present investigation to support the use of stronger (thicker) condoms over standard strength condoms among gay men. The appropriate use of additional lubricant should be encouraged."
Non-latex condoms are not quite as effective as latex condoms and have a higher rate of breaking, meaning their effectiveness is very slightly lower at around 95%. The most common material used for non-latex condoms is polyurethane, but other materials such as lambskin are also sometimes used.
