Can celebrities teach your son or daughter about safe sex? Maybe. The stars featured here have all spoken out about abstinence, using condoms, and getting tested for sexually transmitted diseases — important messages that sex education experts say kids need to hear more. According to the latest U.S. government data, almost half of the 19 million new cases of sexually transmitted diseases each year occur among young adults ages 15 to 24. “When celebrities promote healthy messages about sex — as opposed to modeling risky or negative behaviors — parents have a golden opportunity to share their own values with their kids,” says Good Morning America parenting expert Ann Pleshette Murphy. Whatever your stance on sex ed for teens, you can use these celebs’ headline-making moves as a platform to talk to your kids about their health and behavior.
