Agender? Genderfluid? I don't even know anymore

I remember dressing up to go to parties etc when I was a few years younger, and feeling so feminine and happy to be so, but normally, I don't feel feminine. I never feel definitely male or definitely female.
Recently, I bought some new clothes which I loved at the time, because I never really wear female clothes, and I thought it'd be fun to recreate that feminine feeling from before, but on the day I'd planned to wear them, I ended up choosing to wear baggy jeans and a guys T-shirt instead, because the new clothes were 'too feminine' for me.
The next day, however, I wore the new clothes and loved it.
Normally, I wear feminine makeup and hairstyle, but male clothes and shoes. I have fully crossdressed (ftm makeup and hairstyles to make my hair look short) a few times, and I loved it, but I don't get the urge to do it every day.

I know I am female, but I'm beginning to wonder if that is purely because I am biologically female, I cannot imagine anything else. So, basically, I was hoping for some advice to help me come to a conclusion.

Am I agender, or genderfluid, or am I just rejecting gender roles? I'm not really sure. Any help would be greatly appreciated. Thanks for reading.
