To bring us back to the real world
www.menshealth.co.uk/sex/your-penis/is-your-penis-too-small-9248 states that measured erect and from top it is 5.03 inches.
Mine is 6.5 and I usually get compliments. Though mostly it is around my unusual girth (6 inches) where they are impressed and shocked when I struggle to slide on a condom.
The guys I have been with were usually around 5 inches, a couple at 4 inches, two at six, one at 6.5 and one at 7 (my current partner)
I think stories are exaggerated, from women or men, and again measuring incorrectly skewed the data.
