My wife told me this story about a guy she was dating before me. He had a VERY small one. Like an inch. Funny he was a Body Builder too. ( I'm not one I'm fat ). And my wife said she had to really try hard not to laugh at the guy.
She told me a story where he would talk smak about how big he was. He would like tell her " you want this big old thing " and all the time be holding his stump with two fingers like it's a fire hose.
