Grower, Not A Shower

Never put much thought into the size of my dick when limp until my wife embarrassed the shot out of me during a dumb truth or dare card game with a bunch of our friends. I forget the exact question she got but it had to do with something shocking about your significant other.
She said, "let me start by saying my husband is well endowed,,, when erect. Which made the first time seeing him without an erection even more shocking. It doesn't even look like it belongs to the same man."
Suffice it to say, I was oddly humiliated. I have measured my cock when hard and felt good about myself, so my wife putting it out there that my dick shrinks to oddly small levels when soft shouldn't bother me, but it does for some odd reason.
