Abstinence is as they like to tell you. But really most of the margin for infection for condoms is the result of poor use.

Yes the quoted effectiveness is based on the average in practice. Anecdotally what I've seen is the failure of condoms is usually got drunk and didn't use one. In particular substance abuse is highly correlated with unsafe sex and HIV infection. I'm pretty sure it's also correlated with birth control failure.

Ok sure, abstinence, but talk about cutting off your nose to spite your face.
