Life is full of risks. All sex carries certain risks – chief among them risk of pregnancy, followed by the risk of sexually transmitted infections. Part one deals with pregnancy, part two, STDs.
Pregnancy is without question the most serious of these potential consequences. There are few diseases, and no sexually transmitted ones (except perhaps HPV induced cancers) that can change your life as drastically as the addition of a child. Potential fathers need pay special attention to this warning. Potential mothers have recourse to plan b, termination, and adoption, all of which can have short and long-term consequences of their own that are very significant. Men ought to do their part to avoid putting the people they love in a position where they have to choose from a variety of bad outcomes.
Aside from this, men run a risk of becoming resentful at their partners for their own lack of power over the decision of what to do in the event of an unwanted pregnancy. Even the most carefully laid contingency plan can be tossed out the window without warning when ladies face the reality of a child, their child, living inside of them. Regardless of her decision, whether according to previous plans or not, the inequality of power over that decision can lead to serious strife within a relationship.
The effectiveness of birth control is overstated significantly when perfect use statistics are cited. Typical use statistics represent data collected from consumers in real world conditions, while perfect use statistics are gained using trained personnel, frequently PHD or MD students, in controlled and/or somewhat observed environments.
The most effective forms of birth control are the shot and IUDs. Their effectiveness in the lab and on the street is identical or nearly so, and they’re more 99% effective. That means that only 1% of couples, having sex an average of three times a week, will get pregnant within the first year of relying on any of these as their lone form of birth control.
The pill is 99% effective when used perfectly, but there are a lot of ways to make a mistake beyond simply forgetting to take multiple pills. Additionally, studies have shown that women are most likely to make such a mistake during their fertile periods. As a result of these and other factors, fully 8% of couples that rely on the birth control pill as their lone form of birth control are pregnant within 1 year.
Condoms are also highly effective when used perfectly. It is more difficult to explain in kind terms why their typical use effectiveness is only 85%, a mere 10% better than natural family planning/the rhythm method. Most likely failure to use condoms all together on one or more occasion over the course of the year and undetected breakages (perhaps due to intoxication) make up most of the lost effectiveness.
The hard facts are that 15% of “just condoms” and 8% of “just the pill” end up pregnant. Combining the pill and condoms, with typical use, results in a pregnancy risk of only 1.2%, nearly as good as the shot or an IUD.
Within traditional relationships, unwanted pregnancies affect the people responsible for them. It is even more important in ethical polyamory to take responsible precaution at all times because the consequences of an unwanted pregnancy will reverberate through the poly network, potentially harming the relationships of people who were not directly or indirectly responsible for the pregnancy. Even the most carefully developed compersive attitude can be strained and overcome by the jealousy potentially occasioned by a child.
To sum up, the ethical practice of polyamory virtually requires two forms of birth control, usually including condom, outside the primary couple pair, for reasons of pregnancy prevention alone. There is no more serious risk than unwanted pregnancy for the polyamorous individual, and both partners must be responsible for their portion of pregnancy prevention.
