I definitely agree with what you said about it being ok to want to feel more 'masculine' one day and more feminine' the other. I don't consider myself to be genderfluid, and I'm actually a heterosexual cis female, and even I like to wear baggier clothes and just put my hair in a simple bun and not wear any makeup sometimes, just like sometimes I love to wear nice sandals and paint my nails and put lots of effort into my hair. Label-lessness FTW!
