Parents continue to underestimate the influence they have over their children's decisions about sex, according to new survey data released by the National Campaign to Prevent Teen Pregnancy. While the majority of teens say parents most influence their sexual decisions, parents believe that teens' friends are most influential.

The survey also reveals that most teens (88%) say that it would be easier for them to postpone sexual activity and avoid teen pregnancy if they were able to have more open, honest conversations about these topics with their parents, yet nearly one in four (23%) of teens say they have never discussed sex, contraception, or pregnancy with their parents. Six out of ten teens (59%) surveyed also said that their parents are their role models for healthy, responsible relationships. And one in five young adolescents (aged 12-14) report they have been at a party in the past six months with boys and girls where there were no adults in the house.
