I'm pretty sure that we have all heard at least one of the ways to guess how well a guy is endowed. In my case two of the methods I have heard do seem to work but I'm just wondering if my cas is just a coincidence or if this is generally true. Method 1 : The size of a man's erect cock is about the distance from the tip of the thumb to the tip of th index finger when making a "L". Method 2: The size of a man's erect cock is about three times the length of his thumb. Both of those do come fairly close to my endowment so what's the verdict in your case?
