Help me find a fic.

I can't find a certain fic and it's driving me crazy.
Rimmer and Lister were exposed to a "gay virus" similar to the luck virus and sexual attraction virus.
Cue a long argument about whether Lister had caught the virus. I remember Rimmer saying that Lister had a gay walk.
They finally decide to watch porn to test if they've caught it.

One line I remember was "Rimmer realized there was a gay man standing behind him" or something similar.

It was silly, it was IC, and it was sexy. And I can't find it anywhere.
