As I peruse the various forums in this community, I've come across the topic of men asking their female partners how they size up/compare to previous lovers. You can go two paths with this: "oh you're the biggest i've ever had" and save his ego at the cost of perhaps making it all too big, or "I've had much bigger" at the cost of making him feel like shit. Instead, you should say "one of my lovers was smaller than you, but he was the best sex I've ever had". This way you can get the best of both worlds. His ego will be saved because he is bigger (and frankly, that's what most guys' sexual egos are based on), while at the same time keeping him in check and making him realize he has to work hard to please you and to "compare" with the smaller guy!
