I think with my son he sees that I just love people and especially his Daddy. I don't show too much affection towards anyone else, although I am a very touchy person, so it shouldn't be a big surprise to him. I am speaking about family and love within it rather than sex. I am leaving him to question sex when he is ready. When he is ready I will answer directly and without emotion or judgment, no matter what he asks. I am sure he will ask about mono and if he does, so be it... I will answer. Keeping anything from him is out of the question as I could not call myself poly if I were. Of course I won't go into details, but will keep to the facts and make sure he knows that loving people can be intimate under certain circumstances.
