One major error I’ve heard people make is not realizing pre-ejaculate still contains sperm cells. Maybe not as much as actual semen, but enough. I’ve heard of people having unprotected sex for a good portion of time and then, as they feel they’re reaching climax, they’ll stop and put the condom on. That’s really just my understanding of how people end up pregnant after swearing up and down that whoever had the penis was wearing a condom. Sure they did in the end, but it’s kind of like putting a mask on 15 minutes into being in a room full of sick people. (This is why comprehensive sex education matters)
Also keep in mind that when they say with perfect usage what they mean is that the people who had them fail *reported* perfect usage. A reasonable chunk of those people probably did make an error in usage it’s just that either they didn’t know they made a mistake or they were embarrassed about making a mistake so they said they did use it perfectly, therefore it must be the condoms fault. There were no researchers watching people shag to make sure they were using the condoms correctly.
