Slugs do not have a gender, that is, every slug has both, male and female. But for some reason they still need to be two to produce offspring. They have an opening where one can fertilize the other. They just snuggle together and exchange slimy slug body fluids.
I found a documentary on slug mating on youtube. (Ignore the "related" videos in the side bar. They are rather uncouth examples of human mating.) http://funadvice.com/r/153spdbhcfo
