Secrets of the Phallus: Why Is the Penis Shaped Like That?: Scientific American

http://www.scientificamerican.com/article.cfm?id=secrets-of-the-phallus

A neat find by the newly-squeamish BobbyVardar about the anatomy of the human penis. After reading the term “cervical mucus”, I have to admit to feeling a bit queasy myself, but it is interesting stuff. Also, they provide a handy recipe for making your own seminal fluid – perfect for those of us who don’t generate it on our own, or perhaps for craft time with the kids? (OK, thoroughly squicked now.)

Having spent the first five years of my academic life studying great ape social cognition, I’ve seen more simian penises than I care to mention. I once spent a summer with a 450-pound silverback gorilla that was hung like a wasp (great guy, though) and baby-sat a lascivious young orangutan that liked to insert his penis in just about anything with a hole, which unfortunately one day included my ear.

(So sticking one’s penis into things is both a primal and primate urge!)
