I remember reading a creepypasta with basically that plot. A person (story was written in first person, details carefully avoided, so until the very end you could believe that it was about an infertile woman) trying to get pregnant, getting fucked with no protection, later going as far as injecting semen directly into where they thought their womb would be. And in the end it's revealed that the protagonist was a man all along.

It's not the kinda fictional story I want to see coming true. Seriously, can somebody else's reading material start coming true instead? Someone's who doesn't read almost strictly horror and porn?
