Have you had “the talk” with your kids yet? And do you know what they’re learning at school?

Recent data suggests that schools in many nations are falling short in educating young people effectively about sex and relationships.

Researchers surveyed students from 10 countries around the world, including the U.S., and found that kids felt current teachings didn’t cover the reality about teens and sexuality, transgender and homosexuality.

Here are some tips on how you can get the conversation started with your kids:

• For parents of boys, I recommend asking them open-ended questions like, “Tell me what you’re learning in health class?” or “How much do you think you know about sex?”

• For girls, the American Congress of Obstetricians and Gynecologists recommends they see a gynecologist by age 15 to help cover some of these issues.
