Female Pirate, ally or enemy?

I hit a trigger that had sent me back in time to the pirate era, but not just any pirate age. It was known as the Golden age of piracy, a notorious era where pirates ruled the sea. Not only that but I ended up running into some interesting pirates. Anne Bonny and Mary Read. At first I was confused by their name, because in my perspective they looked men but I was fairly certain they were female. I ran into them at the wrong time though.. I was under the deck when I met them, everyone else aboard the ship were up above. They didn't enjoy my interruption of their own private time and immediately attacked me. I tried to tell them that this was a mistake and that I wouldn't do anything to jeopardize their identity. To be fair although they dressed like men, they were actually pretty feminine. Even if they had put on men clothing to try and cover up any part of being a women I could still tell it apart. In truth they were very aggressive as well as strong. During this time people didn't really agree with the fact that women went out into sea, and so they started dressing themselves up as men so that they could join these pirate crews.
