There was never a rule in our house really, my youngest had a few "boyfriends" when they would go to the local movies and talk on the phone and that was about it, she is now 15 and could care less for a boyfriend, my college age daughter had 2 -4 "boyfriends" at a younger age but high school not until she was a junior did she get
serious with someone they broke up and when she was a senior she found someone else, which I told her was a bad idea
cause she was going away to college well now she is away to college she is finding all kinds of ways to see the boyfriend here at home.
