Across the numerous studies, between 17 per cent and 51.1 per cent of people reported putting a condom on after intercourse has already begun. (Which doesn't quite cut it when it comes to STD prevention.)
Between 13.6 per cent and 44.7 per cent of the respondents reported removing the condom before intercourse was complete.
Between 2.1 per cent and 25.3 per cent of people admitted to completely unrolling the condom before sliding it on. How does that even work?
Failing to leave space for semen at the tip of the condom was reported by 24.3 to 45.7 per cent of the respondents.
When looking back to their last sexual encounter, 48.1 per cent of women and 41.6 per cent of men reported that they didn’t squeeze the air from the tip before use.
Between 4 per cent and 30.4 per cent of participants reported they began rolling the condom on inside out, but then flipped it over and continued its use. And that’s bad, since it can expose her to your pre-ejaculatory fluids, which can get her pregnant. (Nope, that wasn’t just a lie your gym teacher told you.)
When looking back to their last sexual encounter, 11.2 per cent of women and 8.8 per cent of men had began intercourse before the condom was unrolled all the way.
Between 2.1 per cent and 11.2 per cent of people had opened condom packets with sharp objects. The problem: If it’s sharp enough to rip the wrapper, it’s sharp enough to rip the condom. Duh.
When removing the condom from the package, 82.7 per cent of women and 74.5 per cent of men reported that they fail to check for damage before use. What to look for: Make sure the wrapper isn’t worn down or ripped open, keep your eyes peeled for expired dates, and check for visible imperfections while unrolling.
Between 16 per cent and 25.8 per cent of people reported using condoms without lubrication. The trouble? If you’re having sex for an extended period of time, the condom is more likely to tear without lubrication.
Nearly 31 per cent of men and 27 per cent of women reported that (post-sex) they failed to promptly and properly withdraw after ejaculation. No matter what the Cranberries sang, guys, this ain’t a time to let it linger.
Between 1.4 per cent and 3.3 per cent of people reported reusing a condom at least twice during a sexual encounter. Gross.
Between 3.3 per cent and 19.1 per cent of people in the studies had stored their condoms in conditions that did not comply with the recommendations on the package. Avoid storing them in direct sunlight or your wallet – both can degrade the latex.
This wasn’t actually part of the study, but we should add that #15 is this: Not using one at all. According to the (most recent) National Survey of Sexual Health and Behaviour, only 45 per cent of men ages 18 to 24 used a condom with their last sexual partner. And as the age groups increased, the stats only got worse: Only 29.3 per cent of men ages 25 to 34 used condoms and 21.3 per cent of men between ages 35 and 44.
