Things like personal feelings or sex are awkward to discuss with anyone, let alone a parent. This can be a great opportunity for two people to focus on their connection, and not on the rules and expectations that can come along with traditional titles. Think about it before continuing. Your parents are an important resource for information and support. You flirt over text, hook up with guys who are supposed to be 'just friends' and explore your connections with men in more natural and casual settings that rarely involve formal dates.
After they've told you, they'll probably finish with "why?
Talking to Your Parents - or Other Adults
Note that you shouldn't just tell one parent, the other will get to hear eventually and feel angry that you never told them. Some parents have troubles of their own. Maybe you need to break bad news to a parent, like getting a speeding ticket or failing an exam. Whatever you agree to with your parents, make sure you follow through. Be sure to prepare yourself for this too, you don't want to cave in under all the pressure.
