How Was Odo Able To Have Sex With a Human?
...In the Season 5 episode A Simple Investigation, where he loses his human form virginity to the undercover agent infiltrating the Orion Syndicate. This was after he reverted back to his Changling form, caused by the dying Changling infant he was caring for merging with his DNA structure.
So was he still half-human following the merging or did the writers simply overlook that he was a full Changling again? I can't grasp how a Changling devoid of blood, semen, and human sensations like hunger, could have sex like a human.
