I found this in the Washington Post and thought it was interesting:
Teenagers who take virginity pledges—public declarations to abstain from sex—are almost as likely to be infected with a sexually transmitted disease as those who never made the pledge, an eight-year study released yesterday found.
Although young people who sign a virginity pledge delay the initiation of sexual activity, marry at younger ages and have fewer sexual partners, they are also less likely to use condoms and more likely to experiment with oral and anal sex, said the researchers from Yale and Columbia universities.
“The sad story is that kids who are trying to preserve their technical virginity are, in some cases, engaging in much riskier behavior,” said lead author Peter S. Bearman, a professor at Columbia’s Institute for Social and Economic Research and Policy. “From a public health point of view, an abstinence movement that encourages no vaginal sex may inadvertently encourage other forms at sex that are at higher risk of STDs.”
