This is pretty normal. Protecting her from other possible males - doesn't matter if they are human. Doesn't even matter if they are male or female. This could get ugly fast and can turn to severe aggression. If you are not planning on breeding them I suggest you get them spayed/neutered as to not promote any behavioral issues.
