Changeling Sex

Deep Space Nine is the Trek spin-off which broke all the rules.  And along the way, it made up an entire new galaxy of them.  The show's primary action was based on a space station - which wasn't even of Starfleet design nor controlled by the UFP - United Federation of Planets.  A myriad of cool and bizarre alien races all met on the always breaking down DS9 or by its Cardassian name, Terok Nor.  Here, they laughed, cried, fought and loved in every way imaginable.  Among them was Constable Odo - the Changeling or one of the Founders.

Played by actor Rene Auberjonois, Odo could shift his jelly like form into anything imaginable.  When he encountered another changeling, they'd merge together into a smaller version of what they called The Great Link - or the gathering of all of their people into one great lake like body of oozing, gelatinous matter.  This linking with one another wasn't simply comfortable, the experience wrapped the participants into an erotic joining so powerful, it nearly made Odo forget his friends and the cause he fought for - that of liberation from his own race, who had subjugated the residents of DS9.
