My son went to co-ed, and many of the young high school girls could not wait to have a boyfriend.
Some even got more than that!
I prefer a all boys or all girls....they are there to get an education, and the opposite sex will distract.
It has...and will continue.
At that age, young people are trying to find 'who' they are?
So why would they need any more confusing issues.Once they have that all important education, that's up to them what they do with it.
They also have problems with each other, and some girls become overwhelmed, with feelings .Esp when a boy may dump her.
Difficult times, and young people need all the help they can get.
Focus on one thing at a time,plenty of time to have a special person in their lives.
