Although condoms can lead to safer sex, they are not always fool proof. Condom failure ranges from ten to eighty percent when it comes to STD’s. Percentages varies with the type of STD you come in contact with.

This means if you are supposedly having “safe sex” (using a condom) you are still at risk for contracting an STD by possibly an open wound or cracked skin.
