I never knew I was well hung. Even while I was a singer in a rock band--okay, I was shy.
One evening, I was a party at my brother's house.
At one point, I was standing next to my brother, and in context of the conversation he said, "(NAME) doesn't wear any underwear." (NAME) being me.
I stood there not knowing what to think. "What is he talking about? I do wear underwear," I thought to myself. "How would he know anyway?"
I didn't understand it for years. Until one early evening, after a sound check at a club, two girls walked up to me and commented on my budge. It was delightful news to me.
Some years later I remembered what my brother said: and the only reason I could think of for his comment, was that he trying to under-size me in company.
