Using condoms incorrectly?

Hannah • Fur mamma. Heathen.

Condoms work as a barrier to prevent semen from entering the vagina to fertilize an egg. Condoms are 98% effective when always used correctly but only 82% effective (or less) when not always used correctly.

Got this insight from glow when I logged using a condom. This is our first time using condoms and I was just wondering how they could be used incorrectly??

Thanks!
