Small guys: what are your hung big fantasies?

I'm hung and my favorite part is when I'm in the gym locker room with a friend or coworker for the first time and get naked. I love watching them trying not to get caught looking when they realize how much more hung I am than them.

What are your specific fantasies about being hung? Having other people know it? The power? Fucking/dominating someone with your big cock? Be specific!
