My navel (standing straight up) is only 2 inches away form the tip. My length is 7.5 NBPEL, so my dick has to be near 10 inches to touch it.
I’m 5’ 11” and 3/4, so basically 6’ tall, I have a long torso which places my bb further up from the base of my penis. Mine is less then a 1/2 inch from covering my bb and if I had to guess I’d say I’m around 8.5”-9” respectively. Well hung for a skinny fellow, 6’ 135lbs
