I responded to a comment (seen below) along these lines that appeared in US News and World report.
The only "pledge" worth having or doing is this. It's for and done by the young boy to the young girl intimately, repeated over and over (perhaps with different girls) until marriage.
I love being intimate with you. I love hand-holding. I love kissing you. I love holding you. And I PROMISE I WILL NOT TRY TO TAKE OUR INTIMACY TO ANY LEVEL THAT WOULD HURT YOU, MAKE YOU UNCOMFORTABLE OR MAKE YOU REGRETFUL OF WHAT WE DID. I PROMISE.

The problem I see with the first comment on this page is that it only addresses part of the issue. I don't mean to be dismissive of it because it raises an important point but it is incomplete. It doesn't address the procreative aspect of sexuality or the broader impact private sexual decisions have on society at large. Most discussions about sex education programs only address the prevention of sexual assault, pregnancies and disease. These are important but not sufficient.
People who routinely engage in pre-marital sex with multiple partners have a harder time (in general) forming the kind of stable partnerships that are best environment for raising children. For example, studies show couples that cohabitate before marriage have dramatically higher divorce rates. Divorce has a huge impact on the emotional health, economic well-being and social development of children. Because society at large bears many of the consequences of failed marriages and single parenthood, we have a vested interest in promoting the institution of marriage and in doing all we can to encourage teens to wait until marriage for sexual intimacy . If this study is used to further the notion that it is impossible the diminish the percentage of teenagers that engage in teen-sex we are on a dangerous path. If pledges don't work then we should look at some of the points in this article and seriously consider what can be done. Disease and un-wanted pregnancy are not the only risks of pre-marital sex. The risk of extra-marital sex poses to the stability of family units is another factor to be taken into account.
