	Elephants have a very interesting mechanism. Two sets of muscles
which are rudimentary in humans are fully developed to good use in bull
elephants.  In the case of elephants, thrusting would in fact probably
severely injure the female.  However, the elephant's penis, thanks to the
aforementioned adaptation is capable of thrusting forward and back while
the hips remain motionless.  Furthermore, these same muscles retract the
penis into a body cavity of sorts when it is "not in use."
