I was reading this book on potty training (sorry can't remember what the title is) but they talked about kids having a fear of losing what they have worked so hard to produce. Talk to him about why he gets to wear underwear. Maybe ask him where he thinks his bowel movements go. One of the biggest things I have started with my son is taking him to the bathroom with me and letting him flush the toilet and say "bye-bye."
I have heard that boys are harder to potty train before 3, but I am working on my son now so that I can have him potty trained shortly after 2.
I can find the title of the book that I got and let you know. :)
