I have a dilemma. I have a nephew who is ten, and he has been studying his upcoming developmental changes at school, so naturally, he has a lot of questions. My Sister in law would like me to be the one to give him answers, because after all, I was a young boy once, and she was not. His Dad has never been in his life, so I try to be the male role model he needs. The problem is, first, how do I approach the subject in the least uncomfortable way, and second, How in depth do you get on the subject with a ten year old? My two boys are too young for this particular topic, so I do not have any experience to draw on besides the very uncomfortable and poorly executed talk my father gave me when I was eight.
