One who enjoys sex with gerbils. Usually involves the insertion of a gerbil into one's anus which results in stimulation produced by the struggling gerbil. Longer-tailed gerbils are preferred, leaving plenty of room for removing the gerbil from the anus.
After a long session with gerbils last night, one was missing, so I ended up in the Emergency Room having to expain that I was a gerbisexual.
