My wife told her family and friends that I have a small cock.
I have always known that I have a small cock. When I was 14, both my 12 year old and 10 year old brothers had larger cocks than I did. Even my mom, in a truly concerned tone, told me that she was sure it would eventually grow. It grew to about 4" and no more. My wife admitted that she shared my size with her friends, her sisters, and her mom. I think it she did it out of frustration but instead of being ashamed or embarrassed, I was incredibly turned on that they knew. Some of her friends made comments about size but what really surprised me was her mom. When nobody else was around, she would wave her pinky at me with a little wink and I knew she meant it to tease me about my cock size! She eventually became emboldened, gesturing with her pinky regardless of who was there (other than her husband) and still does it years later.
