Hensley
10 is an age of being overly sensitive. I went through it with my son about two years ago and I am now going through it with my daughter. I am sure it has something to do with changing hormones, but he probably hasn't hit puberty quite yet. However, it may be time to talk about what is going to start happening to his body and reasons on how these changes can behind what he may be feeling right now. Good luck...Be prepared for the rollercoaster of changes to come!
