I told my daughter she's not allowed to have boys over to visit her in her room she's 14. She has girl friends come over and occasionally there's boys with them, boys are not allowed to go into her room, plain and simple. I warned her, If they do, the door would be taken off this is about setting boundaries and enforcing them. It's also about teens who don't make the wisest decisions. Appropriate privacy (modesty and changing clothes) is a right all other privacy is a privilege.
