Can you keep up with your childs friends.

I dont have any children yet but I would have sat (as I know you have) him down and spoken to him about the issues involved.Thats the best you can do .I think once you have done that he will be guided by you counsel.Personally I wouldnt worry too much after that ,he is young and exploring his options.Now is the time to do that.It is my belief that it is best you explore your options (safely now) rather than later when you may be involved in a more binding relationship.So put your foot down in terms of counseling but allow him room to make his decisions as an adult.I suspect you have to be tactful (but forceful) so you dont hurt his feelings he may be in a sensitive phase.I am assuming he is an adolescent.I know you may be worried about the girl's feeling as you strive to teach him respect for women and all, but unfortunately , hurt is involved in lfe too and hopefully she will learn too from this experience.This is the safe zone in which both may explore and find a suitable platform from which to launch their lives. Those are my two penny words on the situation ,dont know if I am the best to offer advice on such matters but there you have it .
