Original sentence: Some groups, notably some American evangelical Christians and the Roman Catholic Church oppose sex outside marriage, and object to safe-sex education programs because they believe that providing such education promotes what they call immoral sex.This can place some teenagers at higher risk of unintended pregnancy and STDs, because up to 60 percent of teenagers who pledge virginity until marriage do engage in pre-marital sex and are then one-third less likely to use contraceptives than their peers who have received more traditional sex education.Thus, abstinence from sexual behavior does not guarantee protection against STDs.but was stopped by the religious right
