Okay, I understand your alarm - you're probably thinking something along the lines of WTF, you're saying condoms aren't effective, why are you contradicting sex ed? If you want one quick reference to show you why you should be concerned about this, the Journal of Family Practice published a research survey that revealed the aftermath of these condom myths. I added it to the comment you were responding to. As for why I said what I said in the last comment: I tried finding a condom study that ran for longer than a year. I couldn't find one anywhere. The one year studies gave failure rates that ranged between 2% and 15%. Those figures can be found at Pubmed if you search for condom efficacy.
