The 'idealS' lenghts are inside the averages and large lenghts : 6,7,8, not more than 9"...
But the really ideal penis to me is all about the girth: FAT..6" (bit below, bit above) and uncut.
Than all 'my' lenghts thrustings nice (to my preferences) will make me happy lenght wise...The key will be motion inside my sides, the room they will occupy while doing it...more they press walls more will be 'ideal'...plus foreskin makes uniques 'notes' while pressing it in me.
A banging is not just another banging...it can be a simphony...omg...
