Secrets of the Phallus:

[lordpasternack]

Commented:

"...the human penis is actually an impressive “tool” in the truest sense of the word, one manufactured by nature over hundreds of thousands of years of human evolution."

And continually tampered with by Americans (and to a lesser extent other English-speaking countries besides the UK at present), and those of certain religious persuasions - who think they've found a better model.

"That is to say, if you start with what you see today—in this case, the oddly shaped penis, with its bulbous glans (the “head” in common parlance), its long, rigid shaft, and the coronal ridge..."

...and the bilayered tube of tissue that surrounds the glans while flaccid, secretes and contains natural lubricants, and rolls continuously out across the shaft and back over the glans during sexual activity...

Oh, and the frenulum doesn't attach the "shaft" to the glans - it attaches the FORESKIN to the glans. Frenula serve the purpose of attaching moveable structures to more static structures. The shaft isn't mobile and free enough to require this type of tethering.

The frenulum is also sometimes removed, partially, or pretty much completely, during circumcision - so some men do not possess one.

The remnant of frenulum that most cut men have is part of the remnant of a whole little flap of inner foreskin all around the penis that was left after the initial cut - that has basically "fallen back" onto the shaft and healed against the cut line. This is why the scar is often about an inch or so behind the head, even though the initial cut would likely have been made around point of the corona. This is also why the area between the glans and the cut-line is often pinker in white men than the shaft-skin beneath the cut-line - because it is not actually normal skin: it's pink mucous membrane.

There, I've said my piece. I'm not crusading - simply correcting a few errors and omissions that the author could probably hardly help but make - as well as providing a little more anatomical information to boot.
