Alpha, are you talking about the underside curve length being shortened? In that case i can see your point (though I would argue that most of the length would be non insertable so maybe practically moot, but visually noticeable)
I find that different positions do effect the visual and physical dimensions of my cock.
Honestly I do not get the obsession of knowing each possible max dimension.Most of time you (people in general) won't be there for whatever reason. Factor in the how to measure, following curves, not following them, and it seems like we spend more time quibbling over stupid ass shit that really is not that important in the larger scheme of things. Seriously.
The was a thread here that was referenced earlier today where a member tracked his member in erect and flaccid states and there was like an inch and 3/4 difference in erect lengths, and a 2 inch difference in flaccid.
I know the whole "measure along the top" is a sore spot for you. But at least you don't have a major curve laterally! L has a Left curving U-curve. So by the straight ruler along top side of a perpendicularly held out from the body cock, he is penalized twice!
Since you have access to my pics, you can see the one in comprrison to my hand. My hand is about 7 inches long (measured from heel of palm to tip of middle finger on an ink palm print, slightly longer if i measure from first wrist "ring/bracelet". Along the longer right side, he would be close to 7 1/2-7 3/4. That doesn't even take into account that if i let his cock release it would be pointing up at a,oh lets say 60 degree angle, and curves up. If i factored that underside curve in I would have an even greater number.
Do I do that when I see him? Fuck no. I see a nice cock. If I do take the time to notice his size, I notice how I like how it feels in my hand, or how I like having to struggle to throat him, or how, depending on the position he is either the perfect comfy fit, or a fit that only works because I key of certain pain. I KNOW he has a larger than average to large cock. I truly do no need the most exacting measurements to tell me that! lol


As to the person coming down on Alpha, Mr. bob4400, Alpha has explained to you his stance, and the pics. Let it go. I have a good idea how large his cock is based on a mentally merged image of a multitude of his pics, my knowledge of quarter size, and m knowledge of how light reflects off of objects.
Alpha in your 9 quarter shot the one at the base seems to be at an angle based on how the flash if reflected off of the quarters. You addressed this already by acknowledging that about 8 1/2 were on your dick. I would say closer to 8 1/4 (taking a 1/4 off the last quarter as it is following the curve of your head,where as if you have one straight out there would be a difference between the leading edges of the two quarters, with the one following the curve not quite reaching the leading edge of the non curve following one if a 90 degree vertical line was drawn between them)
The point is, is that even if he is at a tad over 7 1/2 my your estimation, bob, if you factor in underside curves, or hell just BPEL, I think even YOU will agree that him saying his cock is "about 8 inches" is a fair statement.
