Abstinence pledge doesn't really reduce STDs Well, this is no surprise. My favorite parts: 99% of all teens who didn't pledge had sex before marriage...and **% of the teens who DID pledge had sex before marriage. So basically, only 11% actually held up to their end of the pledge. That for Asians, 10.5 percent of virginity pledgers had STDs compared with 5.6 percent of non-pledgers, the biggest gap between pledgers and non-pledgers of all groups, but in the wrong direction. "59 percent of males who did not pledge abstinence used a condom during sex; only 40 percent of male pledgers used a condom." Oy. Looks like virginity pledges aren't really that good after all.
