For another interesting perspective, I recommend the large wallposter
"Penises of the Animal Kingdom".  (I bought it two years ago as a
birthday present for my 14-yr-old Little Brother, for whom this topic
was of unexplainably sudden, obsessive interest. :-)

It proportionally depicts the male copulatory organs of a dozen
mammals, ranging in size from the monster meats of whale and elephant
down to the picayune peckers of man and dog.  All are portrayed in
their fully erect states.

An enclosure supplies a number of anatomical insights; which, I
suppose, could be effectively deployed when party chatter flags.
Among them:

  * The dog penis has a bulbous enlargement that is present only
    during erection.  This bulb is the reason dogs "get stuck" while
    copulating.  The female contracts her vagina around the trapped
    penis to extract seminal fluids.

  * The porpoise has a remarkable penis.  The longer branch of its
    forked end is actually jointed, allowing the tip to rotate or
    swivel.  The animal has voluntary control over this action and
    uses the finger-like appendage to manipulate and investigate
    objects in its environment.

  * Perhaps the oddest penis is that of the pig.  During erection, the
    end of the penis convolutes into a corkscrew bearing an uncanny
    resemblance to the animal's coiled tail.  The helical end of the
    erect organ conforms to the twisted contours of the female's
    vagina.

At the bottom of the enclosure:
