No, you were hired for different reasons. Things evolve. They see you can do more than what you were hired for. Your size and strength seem to matter. Maybe you should ask for a raise because you are doing more.
My point is more if it did go to HR or something they have a way out. They don't have to point to you being a man, but rather you are just the strongest of the group. I don't see how they would be able to do the same in your example of a woman cleaning.
