So I set my goal.
I took a Bounty paper towel roll and cut off a 6 inch piece (it is larger than a toilet paper roll). My penis fits into it snugly, touching the sides of it. My goal is to have my penis to be the length of it (NBP) and for it not to fit inside. Do you think this is a good size penis?
Right now if I just lay a ruler on top of my penis touching the base I am about 4.75.
