possess two penises, which when not being used in the act of copulation
are retracted into the cloaca
. In scientific parlance, each of these is known as a hemipenis
It is difficult to determine the sex of reptiles, but skilled handlers are able to do this by pressing upon the cloaca in such a way as to evert the hemipenes, if they are present. Do not try this without the guidance of a professional, as you may injure your pet.
