Here's an experience that left me crying in the corner in the fetal position:
For a long time, I had operated under the delusion that my penis is a full 6 inches when erect (and I still maintain that it is when fully
erect, YOU JERKS!
), but my girlfriend (the same one from my previous story) didn't think it was quite that long. So one evening, while I was ejoying an esquisite blowjob, she gets the idea to eliminate any sense of manhood I had by pulling out a ruler and proving me wrong.
Just above 5 inches.
When erect but not yet fully
erect YOU JERKS!!!!!
