I think it's better to be on the safer side, and give them enough knowledge on boy/girl relationships, rather than keeping them away from mingling.
So that is my question then. I am sure that being part of a relatively conservative society, we are more protective towards our girls. Because I dont have boyes, so I cant tell but do parents of boys keep the same standards and tell them how frank they can get with other girls or no?
Maybe someone who has both boys and girls as kids can answer that in a better fashion.
