Best response to "you have a big c**k"

My usual response? "I had nothing to do with it. Talk to my mom and dad." :p
 
The compliment was "you are hung like a black man" and I had a foot-in-the-mouth moment and said "thanks..but i have never been with one" :(
 
Is it better to play it off or accept it as a compliment. What would be the most attractive way to react?
Thank you.
I hope you'll enjoy more its use than the view


I have never stated that sentence.
But a usual bedmate confessed me once "You are lucky I'm crazy about big dicks, because you are a bit boring using it"

Since then I have improved a lot
