Parasite/infection/mutation plague

[Morbix]

So let me start by saying my writing sucks so I haven't made this story yet but I have an idea for one that I love very much. Its pretty much like a virus that turns men into gay monsters lol. Its focus is to enter a host so it can pretty much breed and spread through the world making the world its own. But the catch is it can only infect males. I'm not sure yet what it comes from, whether its an alien type of parasite or a man made one or just one thats always been on earth and hasn't developed enough yet. But the main parasite infects a man, by forcing itself down his throat and into his chest where it immediately sends out mini parasites to turn the man into a monster, but its slow. He wakes up and goes out to infect other men. It spreads through saliva/blood/semen/etc so he just grabs the first guy he sees and sticks his tongue into his mouth or something like that. The humans that become infected take longer, because the parasites need to breed inside of the host so it starts out something like the guy gets kissed and pushes the leader host off and then throughout the day starts feeling weird and getting hornier and such and then slowly mutating and wants nothing more than to infect. It spreads like wildfire across the world and as time passes the infected evolve enough to lay eggs inside men who arent infected and then out comes fully developed parasites that can enter and take over you in seconds. It will be full of transformations and monster sex hehe. Let me know what you guys think!
