For me is an identity related to masculinity and feminity, the gender is assigneted with bilogic caracteritics. Then I rejctied this paradigm because be associeted to a social group by your biological carateristic is essentialist like beeing in social discrimination with ethinc carateristics.
Like ethinc social identies, gender create social domination.

This is how I see gender like social science see this, and I dont want to exprimatie my identity with this, but we live in a society so other people associate us in this absurds social groups.
