So here's my dilemma; for the last few years of my life I've questioned my gender. Not the sex, I am a female and don't want to change that, but sometime I feel wrong and feel the need to dress as a man. When I do, I feel better. And then other days I just feel like a girl and dress as such.
I'm so confused. I don't know if I could consider myself a crossdresser, since I do
feel like a boy on the inside some days (I even prefer to go by Erik on those days), it's not just tomboyish or wanting to defy gender-roles. But then do I count as a transgender because I don't feel like a boy all the time. Nor transsexual because I don't want surgery, I'm cissexual, but not cisgendered.
So which am I? Crossdresser or transgender, or is there something else I've not heard of yet?

I appreciate any insight, thoughts or help.
