My 14 year old ds thinks that it is reasonable to let him have 2 girls and one boy sleep round? At the moment I am saying no because I think that the girls mothers will not be happy. My son is NOT sexually active. I have said that I want to talk to the girls parents but my son says that this is deeply embarrassing and "no one does that any more, we're teenagers now, not 5 year olds". He has been very good lately and has helped me out around the house lots today. He is generally quite mature and responsible. Am I being unreasonable?
