Alright, i'll take a rough, clumsy swing at this.
Feeling "male" or feeling "female" really has to do with A) what i'm admiring at the moment (a chainsaw at home depot, or something female like a dress or jewelry, and B) how i'm feeling at the moment, like one of the boys (rarely), or perhaps as a female that I wish I could be. It also encompasses C) wishing that I was a woman (body dysphoria), or being OK with my existing plumbing. Also, there is D) which has to do with who i'm comfortable around. Generally i'm not comfortable around men, but i'm much more comfortable around women.
For me these feelings ebb and flow, so i'd guess that i'm gender fluid.
That's the best I can explain it.
