Every erect penis sticks up at an angle-usually slightly above horizontal.
In youth, the angle is higher. About 10 percent of all males carry the erect penis tightly set against the belly. In 70 percent of men, the hard-on is either horizontal or curved slightly upward.
In most men, the erection is a fairly linear affair, although it is not uncommon for the crank to bend slightly to the left or right.
