Relation between lenght and girth

I read on the internet in the past that when the penis grows in lenght inevitably so does the girth , does anyone knows if this is true and explain me how this mechanism works

Circular(girth) and longitudinal(length) layers of the tunica are interconnected and work with each other.

Increasing one can increase the other.

That might be true to some degree, but there are long thin cocks and long fat cocks and there are short thin cocks and short fat cocks. The combinations are endless. My personal preference is to have a long thick cock! :)

Gprent your talkin about genetics im talking about PE when lenght gains come i read that so does girth ones
