I really don't use gender tags in my character names, because I don't think it's really necessary. The only time I use a species tag in the name is when my character is something not many people would recognize, like "unicorn", "dragon", "manticore", "bobcat", "grey fox", "jaguarundi", and so on.
I don't think it's really necessary for people to use gender tags like "M" or "F", because that's what bios are for. And besides, if your character is obviously a lioness then there's no need for "Lisa F Lioness" in the name description. It would be better if it was just "Lisa."
