ok well i'm 16 and my mom lets my boyfriend come over but gives us no privacy. We only have a living room and no extra room so every 10 minutes she thinks she needs to check on us and she doesn't let me lean on him. I have done nothing to make her not trust me. I'm just trying to say is give your kids a little room just think back to when you were a teen and how you would of loved a little privacy. You can still be pretective without beign controlling.
