For those who have argued that abstinence only based education and taking their daughters to so called Purity Balls in which those daughters take purity pledges - promising to abstain from sex until marriage - change is coming.

Not only are there a number of reports indicating that the Obama presidency will be far more friendly to comprehensive sex ed, but also there are studies that show that abstinence pledges are not enough to stop teens from sexual activity.

According to the study, not only are teens breaking the vow, but also they are less likely to use birth control and therefore are more likely to face an unplanned pregnancy and risk of sexually transmitted diseases.
