This means that: of every 100 women whose partners use condoms, 2 to 15 will become pregnant within the first year of use. So basically, the failure rate does not refer to how many times you have sex, it correlates the number of people (100) who use that method over the course of one year.

Ouch.

I can't tell you how many times people tell me if women had better access to birth control there would be less abortions.
