I suspect that if you ask ten people what gender they feel like and why, that the
why of the answer would be different for each.
At the very least I am quite sure I have no idea what a male feels like, and equally I do not know what a female feels like. I do, however, know what I feel like.
I realise that is not much help, so consider looking for what gender you are by not looking at what gender you are

Perhaps see who you relate to best, and in what role you feel most natural.
As far as I know there are
no activities that determine if you are a girl or boy or not; It is quite possible to have boys who knit and girls who fix cars. (etc.)
Perhaps pay attention to what parts of your body you do not like, if any, and why.
Really the basic idea, I suggest, is to ignore your gender and figure out what you like... and from that see if it points to any gender or the like. ... perhaps that would give you a useful perspective?
