BullDog, Bully or Jules. I also don't mind other terms of endearment when they are good natured.
As to my gender I am butch and/or butch woman. I do not use female identified butch- which I find to be very jargony and seems to be used because of male identified being used. So for those who prefer female identified butch that's fine and I will refer to you that way, but it does not refer to me.
