Bulls Height / Cock Size

My ex's new boyfriend is 6' 4" and of stocky build. I am 5' 10" and slim.

My cock is not bad at 7" but quite slim.

Is cock size related to height / build, ie, will her new boyfriend have a longer / thicker cock than me?

Simple answer is I do not think so. Penis size doesn't relate to general physique in my observations.

I agree with Thug for sure, for sure...I worked in a man's primister and had to do many strip searches of male inmates...it has been my experience that body size has absolutely nothing to do with cock size.
Some huge guy 6'3" tall was only endowed with a 3" cock, while in contrast another guy who could have been a Jockey on a horse race (about 5' tall and weighing about 110 pounds) had a cock that looked to be about 9" while soft....I can only imagine what that would have looked like had it been hard!!!
