Nope...no bone in there. Some animals like the polar bear have a small bone called an oospic. Ask Jack3Beans since he is still up there but I believe in Eskimo culture it is good luck to own one (an oospic that is).

There is no voluntary (striated) muscle in the male pe nis. There is smooth muscle in the vessels but all that 'action' is based on blood filling the 3 'pontoon-like' structures...the 2 corpora cavernosa and the one corpora spongiosum. "Mechanical action" occurs by two nervous pathways...the parasympathetic (P) and the sympathetic (S). Parasympathetic causes erection and sympathetic causes ejaculation, or, as we used in medical school, Point and Shoot.

The new drugs out there like Viagra and Cialis function, they believe, at the arteriole level by increasing nitric oxide. NO or nitric oxide causes vasodilatation or increased blood flow. The results are, well, obvious.
