The droids are just bickering friends. I think the gay couple thing may have started with Mad Magazine's parody, which made Threepio limp wristed, and Artoo complaining he was stuck with a "f*g robot". I'm amazed that it was reprinted around the 20th anniversary with that word intact.
I have a Mad Magazine Sci Fi special from the 1980's which reprints various stories and the word is intact. The Mad about Star Wars book from 2007 changes the word to 'gay'.
