When it comes to size some guys refer to both lenght and girth but a lot of guys admit that they have no idea how thick they are. To me one without the other really doesnt say that much because it takes both measures together to be able to provide the total picture. Most guys know length specifically but when it comes to girth " i dont know but pretty thick" is the best they can do. Some guys dont care about measurement period and that I understand. My question is why if measurement interests you would you not want to know how thick you are if you want to know how long you are? It is so simple. Take the tape that you run along the top of your dick for length and wrap it around and measure the circumference.
