When I was in graduate school, I wondered what changes made erectile tissue in the penis shift from its soft and flexible state to its stiff and inextensible state. Then, with the help of some armadillos, I did the research and figured it out. Tell me what you wonder about, and I’ll see whether I can figure it out for you.
I’ll post answers on Throb as they become available.
