Does your cock reach your navel?

Yes, comfortably.
I'm only 6" from base of cock to navel so most cocks would reach my navel. That is, if they were attached to where mine is attached ...
Well, you know what I mean.

If I bend over and stretch the skin as far as it can go, maybe! I don't think so though.

Mine is even with the navel when standing and 2 inches past when sitting.

Mine touches my navel and I'm 6' 2"

Now, about this height thing... if everyone were built to the same exact proportions it would make sense to compare by height. However since people are built differently, those who are long-waisted have more distance between their cock and navel while those who are short-waisted have less. It would be better to measure that distance.

Mine measured (standing up) from the point where the top of my cock intersects with my body to the bottom of my navel is 7"

Yes but only when hard

Yes, it does.

no. only when sitting and only barely.

6.5"cut
5'8"

Yes

when i'm arroused it does (even though I stick out (not up) when arroused so it hurts to "bend" it up to my navel).

standing no because its curved like a banana, but lying/sitting FUCK yes it does lol by about2-3 inches. Anyone else find that when they are fucking a girl (vaginal/anal) you can actually see the end of your cock puching against her stomch from the inside?

YEA BY ABOUT AN INCH PLUS WHEN LYING ON MY BACK...SEE MY PIC IN MY GALLERY

Yes, it does. I am 6'4".

Yes!
