From having sex with other boys, I don't care if she has sex with other people.
I don't feel the urge to protect her, it's her life.
All my friends always say they will lock up their sister, until they're 18 and maybe then giving them some freedom. I don't get that. It's like the only boyfriend she can have is her dad or her brother.
If she wants to date boys or girls, whatever, and have sex with them, then it's her decision.
I don't care.
