Gay Virus
We have a bunch of bimbo viruses and other universes that change women into complete and utter whores (which I enjoy actually) but what about a universe where the men are forced to be Bi or Gay?
This is a very versatile universe where the settings can rage from only MM to everyone under the sun, even herms or a mutated strand to make guys into dickgirls. so please write have fun with it.
