How do you tell parents about dirty dreams?

It's easy, just tell the truth, they'll understand.

When approaching parents to talk about difficult or embarrassing things, it is wise to pick the right time, when Mom or Dad isn't distracted by a lot of stuff, and when they have time to focus their attention on you. Sometimes when it is just the two of you doing something together, like cleaning up the dishes, or when they are driving you someplace you might find that they are more responsive than when they have a lot of things on their minds. Choose a fairly long drive, of course; not when you are rushing to school or late for soccer practice! - You can begin the conversation by asking about their experiences. Nearly everyone likes to talk about themselves. You could ask, "When you were my age, did you have weird dreams?" You can also encourage their warm feelings for you, by showing your own vulnerability: "I've been feeling bad about something, and I'm not sure how to talk about it." That sort of statement can be very helpful in getting a gentle, caring conversation started.
