Increasing children often have a profound influence on television and movies, this age is such. They will have to realize that apart from the opposite sex, parents are also brothers and sisters. They have to explain with love that the love you are extending in the growing age is only physical attraction, not enduring love.
This is where the real intuition and reconciliation between the two begin. If you can not explain your point to the child properly and you are sticking to the rules, then there can be trouble. At this age children want to live by their own will and they can not tolerate parental control.
