Average age for girls to start dating
In the past, a young man, usually a teenage boy, would come to a teenage girl's house and take her on an actual date which might include something like a movie AND a curfew. Middle schoolers sometimes say they are dating when actually all they are doing is texting or even communicating via Facebook or in some other electronic manner.
This said, it is a simple truth of life that if you act differently from the way the majority does, you will be misunderstood by most.
I'd focus on curfew, I'd limit activities for a 13 year old to 9pm, but might let a 17 yr old stay out until 11 or 12, depending on the individual.
I am a mother of two kids one is 13 and another is 11.
My 13 year old boy already has a girlfriend but with no sexual activity.
My 11 year old daughter found out a boy likes her so she's been telling me stuff.
