Using the correct condom size is really important. Condom sizes that are too big are likely to slip or fall off during use, while condom sizes that are too small are going to feel tight and uncomfortable, reducing the sensation that you feel.

Why do we use codes for our condom sizes, rather than labels like Close Fit, XL or Large? You can learn more by clicking here.
