11. Gex the Gecko series
Thirst Level: 8.95
Finally, a romantic thirst story that ends well! For the longest time Gex attempts to woo Agent Xtra, only to receive nothing in return. It's understandable: we would woo an ex-Baywatch actress, too. (Just in case you didn't know, Agent Xtra was played by Marliece Andrada.) However, your reptilian friend wins in the end, finally earning Xtra's affection in Deep Cover Gecko. You may call it bestiality or inter-species erotica. But we call it love.
