How to tell your parents about self pleasuring?

Honestly why would you? They don't tell you about their sex activities, why would you tell them about yours? Most parents masturbated themselves at younger ages and expect you to do it too. They don't need you to say anything at all since nearly all young people masturbate frequently and with great results and healthy fun times. Share it with your friends and dates but spare your parents the details. lol. No harm in masturbation and no problems for anyone when you pleasure yourselves alone and with no risks of pregnancies or diseases.
