What is Genderfluid?
Genderfluid is actually pretty simple. Your gender changes fluidly from different genders depending on who you are. Some stay with two, some have four, some have six. It really depends on the person.
How can you tell if someone is Genderfluid?
Well for starters you could just ask, it’s not a bad thing to do, so don’t worry. But if you are too nervous to ask, look at clothes, makeup/lack there of, listen for changes in voice too. These might all be changing fairly frequently.
