Well, this and the next picture show the size kings for this page. This man self-measures his erection at nearly 9 inches long and 7 inches around (circumference). This approximately horizontal erection has a swayback curve or u-curve. It is interesting to compare in the next picture an erection of almost exactly the same size, but with a little lower angle and an n-curve. This shows that erection variation still can be rather pronounced even when size is the same. Also these two men give a good illustration of how the penis and erection are not strongly related to body form or development. The model to the left has only modest muscular development whereas the same height man in the next picture has 50 lbs more muscle and a rather heroic mesomorphic build. The model to the left is age 24, 5 ft.11in., 160 lbs.
