I have no idea where this came from, but I'd like a fic in which FtM!Sherlock is accused of rape. (Someone sets him up? Someone's genuinely confused by a similar-looking individual?)

Sherlock could easily disprove the accusations with a quick drop of his pants but doesn't want to risk his secret and have the Yard (and John?) act differently around him as people have done in the past.

Whether or not John knows is up to the author. If there's a pairing, I'd prefer Johnlock or Irene/Sherlock (Irenelock??).
