Shrinking

One night last year my wife and I were in bed and she was playing with my ****. As she was doing this I told her about an article I'd read on WebMD, about how the penis may shrink as a man gets older. The article said the reduction isn't dramatic, but may be noticeable. That a man that has 6" when he is 30 may have 5" or 5.5" inches at 60 years old. (Loosing an inch isn't dramatic? What planet do they live on?) She said " ah, you didn't start out with 6 inches". I said "I know, but do you think my penis is shrinking?" She slowly shook her head up and down and said "yes, I've thought so for awhile, but haven't said anything". She then said, "let's see" and jumps up and gets a ruler and measures me. I asked "what's the verdict?" She started laughing and said, "yup, you are 3 5/8" which means you are 3/8" smaller, but I'll still **** you, at least until you get down to 3.5", then we'll see."

Update: last night she said she thought I was still shrinking. She measured again and I had dropped below her 3.5 inch requirement. We still had sex so I guess earlier it was just an idle threat.
