I'm looking for some terms or phrases that could be used to refer to all the males or all the females collectively and exclusively. Something like a gender-specific version of "mankind" (which usually refers to all humanity with no regards to gender, to the best of my knowledge).
Something like "malekind" and "femalekind", basically.
"_____ (malekind) had its chances with me; I'm moving on to _____ (femalekind)."
"I may have a PhD in Physics, but I will never be able to understand _____ (femalekind)."
(Although that second example could easily just have "women" filling the blank.)
