Many teens have found that it can be a big help to talk to their parents about sex and health. Because your parents know you so well, they can give you advice that is suited to you and answer your questions in a really personal way.
It may not be easy to start the conversation. And if your parents need help talking to you about health and relationships, there's a website just for them! It's got strategies for talking to kids about difficult topics and clear information about important health issues.
TalkWithYourKids.org has lots of resources for adults wanting to build trust with their kids and keep them safe.
