Some parents are really uncomfortable talking about sex. Worse, some threaten or punish their kids for bringing it up. If you feel that asking questions about sex will put you in danger, find another trusted adult to talk to.
If you’re very concerned about your parents’ reaction, you might want to put off the conversation until you feel you and your parents are more ready. Or maybe your parents aren’t around. In these cases, you could turn to another adult you trust, such as a family friend, relative, or counselor.
