I was just having an argument with my friend over whether or not the toilet paper roll test is satisfactory in determining the difference between a thin cock and a thick cock. He argues that if you can fit your cock in the roll then your skinny in his book. While I think that it doesn't mean that much in terms of size. What do u guys think, is your cock automatically skinny if you can fit inside a toilet paper roll? And how big is the average toilet paper roll?
