Mine does only when sitting. It's 8.25" long and the distance from the base of my cock to my navel is a bit over 9 inches when fully extended (standing or laying down). I have a kind of long torso for my height.
Mine does. I remember when I was about 12 there was a rumor that another guy a couple of classes ahead had a dick that reached his navel. We wanted to see it. Mine was close then, but now it does for sure.
I think the standard for membership here is to make it to your navel. Seems like an 8 inch distance for most. I'm a bit short of getting there, unless I sit up so the distance is less.
