While holding mine soft and comparing I am doubtful I could squeeze mine in to a coke can, much less a toilet paper roll. Paper cuts would hurt, but metal cuts...ouch, it is painful to just think about that! Someone wrote that a "magazine" came up with this "test"? Well, lets all go out and do whatever the entertainment media tells us to do...lol. They are such "experts" on everything...and no doubt their "expertise" extends to penis size and such.
The medical profession should just contact "Maxim" and "The E Hollywood Channel" next time they have a question.
And I completely agree with a previous post by Doctor Rock...to paraphrase...just trying is ludicrous and someone should shoot me if I ever degenerate to the point I am stupid enough to try.
