I am gay and I want to come out to my friends and crush, but my parents cannot find out. How do I make sure they don't find out?

Trust me as your Parents will find out real fast once you try to keep it from them so best just to tell them or wait til youre 18 for sure. Once out, you cant undo the secret so make sure you want it out and you definitely don't want your Parents finding out thru the grapevine and not from you as it really causes problems so think about what you really want to do here before you do it. Good luck
