His crazy mind.

Kim
Ok so to be completely honest my fiancé is not that big, but he is not small he's average.he is always telling me he wishes he was big so he could please me more.but in all reality he pleases me fine but I call him big all the time and nothing boots his self confidence about it. What should I do to make him believe that I love his size and that he pleases me just fine and more?!?
