I am a firm believer in the "don`t ask, don`t tell " policy. If your fragile male ego can`t handle the truth, don`t ask. I myself as a younger man made the decision to ask my wife that question, and what answer did I get? The same answer all of you have gotten that asked that question. Unless your significant other has been a nun, she has PROBABLY seen a bigger dick than yours. Kill yourself, hold it against her? Fuck no! YOU asked. Does she stew in bed at night because you have seen bigger titties or had better pussy? probably (surely) not! I think what W.M.P. said was right on the money. When you find someone whom you truly care about and she cares about you, I know the size of your penis is not going to make a shit to her as long as you make her happy.

Besides I sleep just fine, I have a WICKED tongue.
