We soft swapped with a twenty-something couple which was using a condom as their sole method of birth control. Their choice of birth control related to the fact that they were planning on becoming pregnant in the subsequent few months. Full swap under these conditions would have made us nervous (because of the risk of pregnancy).

On their website, Planned Parenthood quotes a CDC study in which condom breakage rates are 2%. Other studies have shown that many people use condoms incorrectly, causing condoms to slip off, etc... and boosting the failure rate to well above 2%.

Assuming 2% is an accurate estimate of condom failure - you can assume that 2% of the time condom users will be at risk of accidental sperm transferral. This risk is mitigated if the breakage is discovered prior to ejaculation. If semen is transferred to the vagina of a fertile women, there is risk of pregnancy (although ovulation must also occurr).

Fortunately, for most swingers, condoms serve as a secondary (redundant) method of birth control. If you combine two birth control methods with an uncorrelated 98% effectiveness, you have an extremely small joint failure rate (because the secondary method will prevent pregnancy 98% of 2% of the time).

The material difference between '2%' (condom alone) and '2% of 2%' (condom and IUD or pill) is a good reason to prefer overlapping birth control methods - one method being a condom and the other being an IUD or pill. Morning after pills are also a good idea.
